fzf(1) fzf - a command-line fuzzy finder fzf(1)
NAME
 fzf - a command-line fuzzy finder
SYNOPSIS
 fzf [options]
DESCRIPTION
 fzf is a general-purpose command-line fuzzy finder.
OPTIONS
 Search mode
 -x, --extended
 Extended-search mode. Since 0.10.9, this is enabled by default. You can disable it with +x or --no-extended.
 -e, --exact
 Enable exact-match
 -i Case-insensitive match (default: smart-case match)
 +i Case-sensitive match
 --literal
 Do not normalize latin script letters for matching.
 --scheme=SCHEME
 Choose scoring scheme tailored for different types of input.
 default Generic scoring scheme designed to work well with any type of input
 path Scoring scheme for paths (additional bonus point only after path separator)
 history Scoring scheme for command history (no additional bonus points).
 Sets --tiebreak=index as well.
 --algo=TYPE
 Fuzzy matching algorithm (default: v2)
 v2 Optimal scoring algorithm (quality)
 v1 Faster but not guaranteed to find the optimal result (performance)
 -n, --nth=N[,..]
 Comma-separated list of field index expressions for limiting search scope. See FIELD INDEX EXPRESSION for the details.
 --with-nth=N[,..]
 Transform the presentation of each line using field index expressions
 -d, --delimiter=STR
 Field delimiter regex for --nth and --with-nth (default: AWK-style)
 --disabled
 Do not perform search. With this option, fzf becomes a simple selector interface rather than a "fuzzy finder". You can later enable the search using enable-search or toggle-
 search action.
 Search result
 +s, --no-sort
 Do not sort the result
 --tac Reverse the order of the input
 e.g.
 history | fzf --tac --no-sort
 --tiebreak=CRI[,..]
 Comma-separated list of sort criteria to apply when the scores are tied.
 length Prefers line with shorter length
 chunk Prefers line with shorter matched chunk (delimited by whitespaces)
 begin Prefers line with matched substring closer to the beginning
 end Prefers line with matched substring closer to the end
 index Prefers line that appeared earlier in the input stream
 - Each criterion should appear only once in the list
 - index is only allowed at the end of the list
 - index is implicitly appended to the list when not specified
 - Default is length (or equivalently length,index)
 - If end is found in the list, fzf will scan each line backwards
 Interface
 -m, --multi
 Enable multi-select with tab/shift-tab. It optionally takes an integer argument which denotes the maximum number of items that can be selected.
 +m, --no-multi
 Disable multi-select
 --no-mouse
 Disable mouse
 --bind=KEYBINDS
 Comma-separated list of custom key bindings. See KEY/EVENT BINDINGS for the details.
 --cycle
 Enable cyclic scroll
 --keep-right
 Keep the right end of the line visible when it's too long. Effective only when the query string is empty.
 --scroll-off=LINES
 Number of screen lines to keep above or below when scrolling to the top or to the bottom (default: 0).
 --no-hscroll
 Disable horizontal scroll
 --hscroll-off=COLS
 Number of screen columns to keep to the right of the highlighted substring (default: 10). Setting it to a large value will cause the text to be positioned on the center of the
 screen.
 --filepath-word
 Make word-wise movements and actions respect path separators. The following actions are affected:
 backward-kill-word
 backward-word
 forward-word
 kill-word
 --jump-labels=CHARS
 Label characters for jump and jump-accept
 Layout
 --height=HEIGHT[%]
 Display fzf window below the cursor with the given height instead of using the full screen.
 --min-height=HEIGHT
 Minimum height when --height is given in percent (default: 10). Ignored when --height is not specified.
 --layout=LAYOUT
 Choose the layout (default: default)
 default Display from the bottom of the screen
 reverse Display from the top of the screen
 reverse-list Display from the top of the screen, prompt at the bottom
 --reverse
 A synonym for --layout=reverse
 --border[=BORDER_OPT]
 Draw border around the finder
 rounded Border with rounded corners (default)
 sharp Border with sharp corners
 horizontal Horizontal lines above and below the finder
 vertical Vertical lines on each side of the finder
 top (up)

 TRBL Same margin for top, right, bottom, and left
 TB,RL Vertical, horizontal margin
 T,RL,B Top, horizontal, bottom margin
 T,R,B,L Top, right, bottom, left margin
 Each part can be given in absolute number or in percentage relative to the terminal size with % suffix.
 e.g.
 fzf --margin 10%
 fzf --margin 1,5%
 --padding=PADDING
 Comma-separated expression for padding inside the border. Padding is distinguishable from margin only when --border option is used.
 e.g.
 fzf --margin 5% --padding 5% --border --preview 'cat {}' \
 --color bg:#222222,preview-bg:#333333
 TRBL Same padding for top, right, bottom, and left
 TB,RL Vertical, horizontal padding

 --no-info
 A synonym for --info=hidden
 --prompt=STR
 Input prompt (default: '> ')
 --pointer=STR
 Pointer to the current line (default: '>')
 --marker=STR
 Multi-select marker (default: '>')
 --header=STR
 The given string will be printed as the sticky header. The lines are displayed in the given order from top to bottom regardless of --layout option, and are not affected by
 --with-nth. ANSI color codes are processed even when --ansi is not set.
 --header-lines=N
 The first N lines of the input are treated as the sticky header. When --with-nth is set, the lines are transformed just like the other lines that follow.

 --color='pointer:#E12672,marker:#E17899,prompt:#98BEDE,hl+:#98BC99'
 --no-bold
 Do not use bold text
 --black
 Use black background
 History
 --history=HISTORY_FILE
 Load search history from the specified file and update the file on completion. When enabled, CTRL-N and CTRL-P are automatically remapped to next-history and previous-history.
 --history-size=N
 Maximum number of entries in the history file (default: 1000). The file is automatically truncated when the number of the lines exceeds the value.
 Preview
 --preview=COMMAND
 Execute the given command for the current line and display the result on the preview window. {} in the command is the placeholder that is replaced to the single-quoted string of
 the current line. To transform the replacement string, specify field index expressions between the braces (See FIELD INDEX EXPRESSION for the details).
 e.g.
 fzf --preview='head -$LINES {}'
 ls -l | fzf --preview="echo user={3} when={-4..-2}; cat {-1}" --header-lines=1
 fzf exports $FZF_PREVIEW_LINES and $FZF_PREVIEW_COLUMNS so that they represent the exact size of the preview window. (It also overrides $LINES and $COLUMNS with the same values
 but they can be reset by the default shell, so prefer to refer to the ones with FZF_PREVIEW_ prefix.)
 A placeholder expression starting with + flag will be replaced to the space-separated list of the selected lines (or the current line if no selection was made) individually
 quoted.
 e.g.
 fzf --multi --preview='head -10 {+}'
 git log --oneline | fzf --multi --preview 'git show {+1}'
 When using a field index expression, leading and trailing whitespace is stripped from the replacement string. To preserve the whitespace, use the s flag.
 Also, {q} is replaced to the current query string, and {n} is replaced to zero-based ordinal index of the line. Use {+n} if you want all index numbers when multiple lines are
 selected.
 A placeholder expression with f flag is replaced to the path of a temporary file that holds the evaluated list. This is useful when you multi-select a large number of items and
 the length of the evaluated string may exceed ARG_MAX.
 e.g.
 # Press CTRL-A to select 100K items and see the sum of all the numbers.
 # This won't work properly without 'f' flag due to ARG_MAX limit.
 seq 100000 | fzf --multi --bind ctrl-a:select-all \
 --preview "awk '{sum+=\$1} END {print sum}' {+f}"
 Note that you can escape a placeholder pattern by prepending a backslash.
 Preview window will be updated even when there is no match for the current query if any of the placeholder expressions evaluates to a non-empty string.
 Since 0.24.0, fzf can render partial preview content before the preview command completes. ANSI escape sequence for clearing the display (CSI 2 J) is supported, so you can use
 it to implement preview window that is constantly updating.
 e.g.
 fzf --preview 'for i in $(seq 100000); do
 (( i % 200 == 0 )) && printf "\033[2J"
 echo "$i"
 sleep 0.01
 done'
 --preview-window=[POSITION][,SIZE[%]][,border-BORDER_OPT][,[no]wrap][,[no]follow][,[no]cycle][,[no]hidden][,+SCROLL[OFFSETS][/DENOM]][,~HEADER_LINES][,default][,<SIZE_THRESHOLD(ALTER‐
 NATIVE_LAYOUT)]
 POSITION: (default: right)
 up
 down
 left
 right
 Determines the layout of the preview window.
 * If the argument contains :hidden, the preview window will be hidden by default until toggle-preview action is triggered.
 * If size is given as 0, preview window will not be visible, but fzf will still execute the command in the background.
 * Long lines are truncated by default. Line wrap can be enabled with wrap flag.
 * Preview window will automatically scroll to the bottom when follow flag is set, similarly to how tail -f works.
 e.g.
 fzf --preview-window follow --preview 'for i in $(seq 100000); do
 echo "$i"
 sleep 0.01
 (( i % 300 == 0 )) && printf "\033[2J"
 done'
 * Cyclic scrolling is enabled with cycle flag.
 * To change the style of the border of the preview window, specify one of the options for --border with border- prefix. e.g. border-rounded (border with rounded edges, de‐
 fault), border-sharp (border with sharp edges), border-left, border-none, etc.
 * [:+SCROLL[OFFSETS][/DENOM]] determines the initial scroll offset of the preview window.
 - SCROLL can be either a numeric integer or a single-field index expression that refers to a numeric integer.
 - The optional OFFSETS part is for adjusting the base offset. It should be given as a series of signed integers (-INTEGER or +INTEGER).
 - The final /DENOM part is for specifying a fraction of the preview window height.
 * ~HEADER_LINES keeps the top N lines as the fixed header so that they are always visible.
 * default resets all options previously set to the default.
 e.g.
 # Non-default scroll window positions and sizes
 fzf --preview="head {}" --preview-window=up,30%
 fzf --preview="file {}" --preview-window=down,1
 # Initial scroll offset is set to the line number of each line of
 # git grep output *minus* 5 lines (-5)
 git grep --line-number '' |
 fzf --delimiter : --preview 'nl {1}' --preview-window '+{2}-5'
 # Preview with bat, matching line in the middle of the window below
 # the fixed header of the top 3 lines
 #
 # ~3 Top 3 lines as the fixed header
 # +{2} Base scroll offset extracted from the second field
 # +3 Extra offset to compensate for the 3-line header
 # /2 Put in the middle of the preview area
 #
 git grep --line-number '' |
 fzf --delimiter : \
 --preview 'bat --style=full --color=always --highlight-line {2} {1}' \
 --preview-window '~3,+{2}+3/2'
 # Display top 3 lines as the fixed header
 fzf --preview 'bat --style=full --color=always {}' --preview-window '~3'
 * You can specify an alternative set of options that are used only when the size
 of the preview window is below a certain threshold. Note that only one
 alternative layout is allowed.
 e.g.
 fzf --preview 'cat {}' --preview-window 'right,border-left,<30(up,30%,border-bottom)'
 Scripting
 -q, --query=STR
 Start the finder with the given query
 -1, --select-1
 If there is only one match for the initial query (--query), do not start interactive finder and automatically select the only match
 -0, --exit-0
 If there is no match for the initial query (--query), do not start interactive finder and exit immediately
 -f, --filter=STR
 Filter mode. Do not start interactive finder. When used with --no-sort, fzf becomes a fuzzy-version of grep.
 --print-query
 Print query as the first line
 --expect=KEY[,..]
 Comma-separated list of keys that can be used to complete fzf in addition to the default enter key. When this option is set, fzf will print the name of the key pressed as the
 first line of its output (or as the second line if --print-query is also used). The line will be empty if fzf is completed with the default enter key. If --expect option is
 specified multiple times, fzf will expect the union of the keys. --no-expect will clear the list.
 e.g.
 fzf --expect=ctrl-v,ctrl-t,alt-s --expect=f1,f2,~,@
 --read0
 Read input delimited by ASCII NUL characters instead of newline characters
 --print0
 Print output delimited by ASCII NUL characters instead of newline characters
 --no-clear
 Do not clear finder interface on exit. If fzf was started in full screen mode, it will not switch back to the original screen, so you'll have to manually run tput rmcup to re‐
 turn. This option can be used to avoid flickering of the screen when your application needs to start fzf multiple times in order.
 --sync Synchronous search for multi-staged filtering. If specified, fzf will launch ncurses finder only after the input stream is complete.
 e.g. fzf --multi | fzf --sync
 --version
 Display version information and exit
 Note that most options have the opposite versions with --no- prefix.
ENVIRONMENT VARIABLES
 FZF_DEFAULT_COMMAND
 Default command to use when input is tty. On *nix systems, fzf runs the command with $SHELL -c if SHELL is set, otherwise with sh -c, so in this case make sure that the command
 is POSIX-compliant.
 FZF_DEFAULT_OPTS
 Default options. e.g. export FZF_DEFAULT_OPTS="--extended --cycle"
EXIT STATUS
 0 Normal exit
 1 No match
 2 Error
 130 Interrupted with CTRL-C or ESC
FIELD INDEX EXPRESSION
 A field index expression can be a non-zero integer or a range expression ([BEGIN]..[END]). --nth and --with-nth take a comma-separated list of field index expressions.
 Examples
 1 The 1st field
 2 The 2nd field
 -1 The last field
 -2 The 2nd to last field
 3..5 From the 3rd field to the 5th field
 2.. From the 2nd field to the last field
 ..-3 From the 1st field to the 3rd to the last field
 .. All the fields
EXTENDED SEARCH MODE
 Unless specified otherwise, fzf will start in "extended-search mode". In this mode, you can specify multiple patterns delimited by spaces, such as: 'wild ^music .mp3$ sbtrkt !rmx
 You can prepend a backslash to a space (\ ) to match a literal space character.
 Exact-match (quoted)
 A term that is prefixed by a single-quote character (') is interpreted as an "exact-match" (or "non-fuzzy") term. fzf will search for the exact occurrences of the string.
 Anchored-match
 A term can be prefixed by ^, or suffixed by $ to become an anchored-match term. Then fzf will search for the lines that start with or end with the given string. An anchored-match term
 is also an exact-match term.
 Negation
 If a term is prefixed by !, fzf will exclude the lines that satisfy the term from the result. In this case, fzf performs exact match by default.
 Exact-match by default
 If you don't prefer fuzzy matching and do not wish to "quote" (prefixing with ') every word, start fzf with -e or --exact option. Note that when --exact is set, '-prefix "unquotes" the
 term.
 OR operator
 A single bar character term acts as an OR operator. For example, the following query matches entries that start with core and end with either go, rb, or py.
 e.g. ^core go$ | rb$ | py$
KEY/EVENT BINDINGS
 --bind option allows you to bind a key or an event to one or more actions. You can use it to customize key bindings or implement dynamic behaviors.
 --bind takes a comma-separated list of binding expressions. Each binding expression is KEY:ACTION or EVENT:ACTION.
 e.g.
 fzf --bind=ctrl-j:accept,ctrl-k:kill-line

 ACTION COMPOSITION
 Multiple actions can be chained using + separator.
 e.g.
 fzf --multi --bind 'ctrl-a:select-all+accept'
 fzf --multi --bind 'ctrl-a:select-all' --bind 'ctrl-a:+accept'
 ACTION ARGUMENT
 An action denoted with (...) suffix takes an argument.
 e.g.
 fzf --bind 'ctrl-a:change-prompt(NewPrompt> )'
 fzf --bind 'ctrl-v:preview(cat {})' --preview-window hidden
 If the argument contains parentheses, fzf may fail to parse the expression. In that case, you can use any of the following alternative notations to avoid parse errors.
 action-name[...]
 action-name~...~
 action-name!...!
 action-name@...@
 action-name#...#
 action-name$...$
 action-name%...%
 action-name^...^
 action-name&...&
 action-name*...*
 action-name;...;
 action-name/.../
 action-name|...|
 action-name:...
 The last one is the special form that frees you from parse errors as it does not expect the closing character. The catch is that it should be the last one in the comma-separated
 list of key-action pairs.
 COMMAND EXECUTION
 With execute(...) action, you can execute arbitrary commands without leaving fzf. For example, you can turn fzf into a simple file browser by binding enter key to less command like
 follows.
 fzf --bind "enter:execute(less {})"
 You can use the same placeholder expressions as in --preview.
 fzf switches to the alternate screen when executing a command. However, if the command is expected to complete quickly, and you are not interested in its output, you might want to use
 execute-silent instead, which silently executes the command without the switching. Note that fzf will not be responsive until the command is complete. For asynchronous execution, start
 your command as a background process (i.e. appending &).
 On *nix systems, fzf runs the command with $SHELL -c if SHELL is set, otherwise with sh -c, so in this case make sure that the command is POSIX-compliant.
 RELOAD INPUT
 reload(...) action is used to dynamically update the input list without restarting fzf. It takes the same command template with placeholder expressions as execute(...).
 See https://github.com/junegunn/fzf/issues/1750 for more info.
 e.g.
 # Update the list of processes by pressing CTRL-R
 ps -ef | fzf --bind 'ctrl-r:reload(ps -ef)' --header 'Press CTRL-R to reload' \
 --header-lines=1 --layout=reverse
 # Integration with ripgrep
 RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
 INITIAL_QUERY="foobar"
 FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \
 fzf --bind "change:reload:$RG_PREFIX {q} || true" \
 --ansi --disabled --query "$INITIAL_QUERY"
 PREVIEW BINDING
 With preview(...) action, you can specify multiple different preview commands in addition to the default preview command given by --preview option.
 e.g.
 # Default preview command with an extra preview binding
 fzf --preview 'file {}' --bind '?:preview:cat {}'
 # A preview binding with no default preview command
 # (Preview window is initially empty)
 fzf --bind '?:preview:cat {}'
 # Preview window hidden by default, it appears when you first hit '?'
 fzf --bind '?:preview:cat {}' --preview-window hidden
 CHANGE PREVIEW WINDOW ATTRIBUTES
 change-preview-window action can be used to change the properties of the preview window. Unlike the --preview-window option, you can specify multiple sets of options separated by '|'
 characters.
 e.g.
 # Rotate through the options using CTRL-/
 fzf --preview 'cat {}' --bind 'ctrl-/:change-preview-window(right,70%|down,40%,border-horizontal|hidden|right)'
 # The default properties given by `--preview-window` are inherited, so an empty string in the list is interpreted as the default
 fzf --preview 'cat {}' --preview-window 'right,40%,border-left' --bind 'ctrl-/:change-preview-window(70%|down,border-top|hidden|)'
 # This is equivalent to toggle-preview action
 fzf --preview 'cat {}' --bind 'ctrl-/:change-preview-window(hidden|)'

fzf(1) fzf - a command-line fuzzy finder fzf(1)
NAME
fzf - a command-line fuzzy finder
SYNOPSIS
fzf [options]
DESCRIPTION
fzf is a general-purpose command-line fuzzy finder.
OPTIONS
Search mode
-x, --extended
Extended-search mode. Since 0.10.9, this is enabled by default. You can disable it with +x or --no-extended.
-e, --exact
Enable exact-match
-i Case-insensitive match (default: smart-case match)
+i Case-sensitive match
--literal
Do not normalize latin script letters for matching.
--scheme=SCHEME
Choose scoring scheme tailored for different types of input.
default Generic scoring scheme designed to work well with any type of input
path Scoring scheme for paths (additional bonus point only after path separator)
history Scoring scheme for command history (no additional bonus points).
Sets --tiebreak=index as well.
--algo=TYPE
Fuzzy matching algorithm (default: v2)
v2 Optimal scoring algorithm (quality)
v1 Faster but not guaranteed to find the optimal result (performance)
-n, --nth=N[,..]
Comma-separated list of field index expressions for limiting search scope. See FIELD INDEX EXPRESSION for the details.
--with-nth=N[,..]
Transform the presentation of each line using field index expressions
-d, --delimiter=STR
Field delimiter regex for --nth and --with-nth (default: AWK-style)
--disabled
Do not perform search. With this option, fzf becomes a simple selector interface rather than a "fuzzy finder". You can later enable the search using enable-search or toggle-
search action.
Search result
+s, --no-sort
Do not sort the result
--tac Reverse the order of the input
e.g.
history | fzf --tac --no-sort
--tiebreak=CRI[,..]
Comma-separated list of sort criteria to apply when the scores are tied.
length Prefers line with shorter length
chunk Prefers line with shorter matched chunk (delimited by whitespaces)
begin Prefers line with matched substring closer to the beginning
end Prefers line with matched substring closer to the end
index Prefers line that appeared earlier in the input stream
- Each criterion should appear only once in the list
- index is only allowed at the end of the list
- index is implicitly appended to the list when not specified
- Default is length (or equivalently length,index)
- If end is found in the list, fzf will scan each line backwards
Interface
-m, --multi
Enable multi-select with tab/shift-tab. It optionally takes an integer argument which denotes the maximum number of items that can be selected.
+m, --no-multi
Disable multi-select
--no-mouse
Disable mouse
--bind=KEYBINDS
Comma-separated list of custom key bindings. See KEY/EVENT BINDINGS for the details.
--cycle
Enable cyclic scroll
--keep-right
Keep the right end of the line visible when it's too long. Effective only when the query string is empty.
--scroll-off=LINES
Number of screen lines to keep above or below when scrolling to the top or to the bottom (default: 0).
--no-hscroll
Disable horizontal scroll
--hscroll-off=COLS
Number of screen columns to keep to the right of the highlighted substring (default: 10). Setting it to a large value will cause the text to be positioned on the center of the
screen.
--filepath-word
Make word-wise movements and actions respect path separators. The following actions are affected:
backward-kill-word
backward-word
forward-word
kill-word
--jump-labels=CHARS
Label characters for jump and jump-accept
Layout
--height=HEIGHT[%]
Display fzf window below the cursor with the given height instead of using the full screen.
--min-height=HEIGHT
Minimum height when --height is given in percent (default: 10). Ignored when --height is not specified.
--layout=LAYOUT
Choose the layout (default: default)
default Display from the bottom of the screen
reverse Display from the top of the screen
reverse-list Display from the top of the screen, prompt at the bottom
--reverse
A synonym for --layout=reverse
--border[=BORDER_OPT]
Draw border around the finder
rounded Border with rounded corners (default)
sharp Border with sharp corners
horizontal Horizontal lines above and below the finder
vertical Vertical lines on each side of the finder
top (up)
bottom (down)
left
right
none
--no-unicode
Use ASCII characters instead of Unicode box drawing characters to draw border
--margin=MARGIN
Comma-separated expression for margins around the finder.
TRBL Same margin for top, right, bottom, and left
TB,RL Vertical, horizontal margin
T,RL,B Top, horizontal, bottom margin
T,R,B,L Top, right, bottom, left margin
Each part can be given in absolute number or in percentage relative to the terminal size with % suffix.
e.g.
fzf --margin 10%
fzf --margin 1,5%
--padding=PADDING
Comma-separated expression for padding inside the border. Padding is distinguishable from margin only when --border option is used.
e.g.
fzf --margin 5% --padding 5% --border --preview 'cat {}' \
--color bg:#222222,preview-bg:#333333
TRBL Same padding for top, right, bottom, and left
TB,RL Vertical, horizontal padding
T,RL,B Top, horizontal, bottom padding
T,R,B,L Top, right, bottom, left padding
--info=STYLE
Determines the display style of finder info.
default Display on the next line to the prompt
inline Display on the same line
hidden Do not display finder info
--no-info
A synonym for --info=hidden
--prompt=STR
Input prompt (default: '> ')
--pointer=STR
Pointer to the current line (default: '>')
--marker=STR
Multi-select marker (default: '>')
--header=STR
The given string will be printed as the sticky header. The lines are displayed in the given order from top to bottom regardless of --layout option, and are not affected by
--with-nth. ANSI color codes are processed even when --ansi is not set.
--header-lines=N
The first N lines of the input are treated as the sticky header. When --with-nth is set, the lines are transformed just like the other lines that follow.
--header-first
Print header before the prompt line
--ellipsis=STR
Ellipsis to show when line is truncated (default: '..')
Display
--ansi Enable processing of ANSI color codes
--tabstop=SPACES
Number of spaces for a tab character (default: 8)
--color=[BASE_SCHEME][,COLOR_NAME[:ANSI_COLOR][:ANSI_ATTRIBUTES]]...
Color configuration. The name of the base color scheme is followed by custom color mappings.
BASE SCHEME:
(default: dark on 256-color terminal, otherwise 16)
dark Color scheme for dark 256-color terminal
light Color scheme for light 256-color terminal
16 Color scheme for 16-color terminal
bw No colors (equivalent to --no-color)
COLOR NAMES:
fg Text
bg Background
preview-fg Preview window text
preview-bg Preview window background
hl Highlighted substrings
fg+ Text (current line)
bg+ Background (current line)
gutter Gutter on the left (defaults to bg+)

--color='pointer:#E12672,marker:#E17899,prompt:#98BEDE,hl+:#98BC99'
--no-bold
Do not use bold text
--black
Use black background
History
--history=HISTORY_FILE
Load search history from the specified file and update the file on completion. When enabled, CTRL-N and CTRL-P are automatically remapped to next-history and previous-history.
--history-size=N
Maximum number of entries in the history file (default: 1000). The file is automatically truncated when the number of the lines exceeds the value.
Preview
--preview=COMMAND
Execute the given command for the current line and display the result on the preview window. {} in the command is the placeholder that is replaced to the single-quoted string of
the current line. To transform the replacement string, specify field index expressions between the braces (See FIELD INDEX EXPRESSION for the details).
e.g.
fzf --preview='head -$LINES {}'
ls -l | fzf --preview="echo user={3} when={-4..-2}; cat {-1}" --header-lines=1
fzf exports $FZF_PREVIEW_LINES and $FZF_PREVIEW_COLUMNS so that they represent the exact size of the preview window. (It also overrides $LINES and $COLUMNS with the same values
but they can be reset by the default shell, so prefer to refer to the ones with FZF_PREVIEW_ prefix.)
A placeholder expression starting with + flag will be replaced to the space-separated list of the selected lines (or the current line if no selection was made) individually
quoted.
e.g.
fzf --multi --preview='head -10 {+}'
git log --oneline | fzf --multi --preview 'git show {+1}'
When using a field index expression, leading and trailing whitespace is stripped from the replacement string. To preserve the whitespace, use the s flag.
Also, {q} is replaced to the current query string, and {n} is replaced to zero-based ordinal index of the line. Use {+n} if you want all index numbers when multiple lines are
selected.
A placeholder expression with f flag is replaced to the path of a temporary file that holds the evaluated list. This is useful when you multi-select a large number of items and
the length of the evaluated string may exceed ARG_MAX.
e.g.
# Press CTRL-A to select 100K items and see the sum of all the numbers.
# This won't work properly without 'f' flag due to ARG_MAX limit.
seq 100000 | fzf --multi --bind ctrl-a:select-all \
--preview "awk '{sum+=\$1} END {print sum}' {+f}"
Note that you can escape a placeholder pattern by prepending a backslash.
Preview window will be updated even when there is no match for the current query if any of the placeholder expressions evaluates to a non-empty string.
Since 0.24.0, fzf can render partial preview content before the preview command completes. ANSI escape sequence for clearing the display (CSI 2 J) is supported, so you can use
it to implement preview window that is constantly updating.
e.g.
fzf --preview 'for i in $(seq 100000); do
(( i % 200 == 0 )) && printf "\033[2J"
echo "$i"
sleep 0.01
done'
--preview-window=[POSITION][,SIZE[%]][,border-BORDER_OPT][,[no]wrap][,[no]follow][,[no]cycle][,[no]hidden][,+SCROLL[OFFSETS][/DENOM]][,~HEADER_LINES][,default][,<SIZE_THRESHOLD(ALTER‐
NATIVE_LAYOUT)]
POSITION: (default: right)

Determines the layout of the preview window.
* If the argument contains :hidden, the preview window will be hidden by default until toggle-preview action is triggered.
* If size is given as 0, preview window will not be visible, but fzf will still execute the command in the background.
* Long lines are truncated by default. Line wrap can be enabled with wrap flag.
* Preview window will automatically scroll to the bottom when follow flag is set, similarly to how tail -f works.
e.g.
fzf --preview-window follow --preview 'for i in $(seq 100000); do
echo "$i"
sleep 0.01
(( i % 300 == 0 )) && printf "\033[2J"
done'
* Cyclic scrolling is enabled with cycle flag.
* To change the style of the border of the preview window, specify one of the options for --border with border- prefix. e.g. border-rounded (border with rounded edges, de‐
fault), border-sharp (border with sharp edges), border-left, border-none, etc.
* [:+SCROLL[OFFSETS][/DENOM]] determines the initial scroll offset of the preview window.
- SCROLL can be either a numeric integer or a single-field index expression that refers to a numeric integer.
- The optional OFFSETS part is for adjusting the base offset. It should be given as a series of signed integers (-INTEGER or +INTEGER).
- The final /DENOM part is for specifying a fraction of the preview window height.
* ~HEADER_LINES keeps the top N lines as the fixed header so that they are always visible.
* default resets all options previously set to the default.
e.g.
# Non-default scroll window positions and sizes
fzf --preview="head {}" --preview-window=up,30%
fzf --preview="file {}" --preview-window=down,1
# Initial scroll offset is set to the line number of each line of
# git grep output *minus* 5 lines (-5)
git grep --line-number '' |
fzf --delimiter : --preview 'nl {1}' --preview-window '+{2}-5'
# Preview with bat, matching line in the middle of the window below
# the fixed header of the top 3 lines
#
# ~3 Top 3 lines as the fixed header
# +{2} Base scroll offset extracted from the second field
# +3 Extra offset to compensate for the 3-line header
# /2 Put in the middle of the preview area
#
git grep --line-number '' |
fzf --delimiter : \
--preview 'bat --style=full --color=always --highlight-line {2} {1}' \
--preview-window '~3,+{2}+3/2'
# Display top 3 lines as the fixed header
fzf --preview 'bat --style=full --color=always {}' --preview-window '~3'
* You can specify an alternative set of options that are used only when the size
of the preview window is below a certain threshold. Note that only one
alternative layout is allowed.
e.g.
fzf --preview 'cat {}' --preview-window 'right,border-left,<30(up,30%,border-bottom)'
Scripting
-q, --query=STR
Start the finder with the given query
-1, --select-1
If there is only one match for the initial query (--query), do not start interactive finder and automatically select the only match
-0, --exit-0
If there is no match for the initial query (--query), do not start interactive finder and exit immediately
-f, --filter=STR
Filter mode. Do not start interactive finder. When used with --no-sort, fzf becomes a fuzzy-version of grep.
--print-query
Print query as the first line
--expect=KEY[,..]
Comma-separated list of keys that can be used to complete fzf in addition to the default enter key. When this option is set, fzf will print the name of the key pressed as the
first line of its output (or as the second line if --print-query is also used). The line will be empty if fzf is completed with the default enter key. If --expect option is
specified multiple times, fzf will expect the union of the keys. --no-expect will clear the list.
e.g.
fzf --expect=ctrl-v,ctrl-t,alt-s --expect=f1,f2,~,@
--read0
Read input delimited by ASCII NUL characters instead of newline characters
--print0
Print output delimited by ASCII NUL characters instead of newline characters
--no-clear
Do not clear finder interface on exit. If fzf was started in full screen mode, it will not switch back to the original screen, so you'll have to manually run tput rmcup to re‐
turn. This option can be used to avoid flickering of the screen when your application needs to start fzf multiple times in order.
--sync Synchronous search for multi-staged filtering. If specified, fzf will launch ncurses finder only after the input stream is complete.
e.g. fzf --multi | fzf --sync
--version
Display version information and exit
Note that most options have the opposite versions with --no- prefix.
ENVIRONMENT VARIABLES
FZF_DEFAULT_COMMAND
Default command to use when input is tty. On *nix systems, fzf runs the command with $SHELL -c if SHELL is set, otherwise with sh -c, so in this case make sure that the command
is POSIX-compliant.
FZF_DEFAULT_OPTS
Default options. e.g. export FZF_DEFAULT_OPTS="--extended --cycle"
EXIT STATUS
0 Normal exit
1 No match
2 Error
130 Interrupted with CTRL-C or ESC
FIELD INDEX EXPRESSION
A field index expression can be a non-zero integer or a range expression ([BEGIN]..[END]). --nth and --with-nth take a comma-separated list of field index expressions.
Examples
1 The 1st field
2 The 2nd field
-1 The last field
-2 The 2nd to last field
3..5 From the 3rd field to the 5th field
2.. From the 2nd field to the last field
..-3 From the 1st field to the 3rd to the last field
.. All the fields
EXTENDED SEARCH MODE
Unless specified otherwise, fzf will start in "extended-search mode". In this mode, you can specify multiple patterns delimited by spaces, such as: 'wild ^music .mp3$ sbtrkt !rmx
You can prepend a backslash to a space (\ ) to match a literal space character.
Exact-match (quoted)
A term that is prefixed by a single-quote character (') is interpreted as an "exact-match" (or "non-fuzzy") term. fzf will search for the exact occurrences of the string.
Anchored-match
A term can be prefixed by ^, or suffixed by $ to become an anchored-match term. Then fzf will search for the lines that start with or end with the given string. An anchored-match term
is also an exact-match term.
Negation
If a term is prefixed by !, fzf will exclude the lines that satisfy the term from the result. In this case, fzf performs exact match by default.
Exact-match by default
If you don't prefer fuzzy matching and do not wish to "quote" (prefixing with ') every word, start fzf with -e or --exact option. Note that when --exact is set, '-prefix "unquotes" the
term.
OR operator
A single bar character term acts as an OR operator. For example, the following query matches entries that start with core and end with either go, rb, or py.
e.g. ^core go$ | rb$ | py$
KEY/EVENT BINDINGS
--bind option allows you to bind a key or an event to one or more actions. You can use it to customize key bindings or implement dynamic behaviors.
--bind takes a comma-separated list of binding expressions. Each binding expression is KEY:ACTION or EVENT:ACTION.
e.g.
fzf --bind=ctrl-j:accept,ctrl-k:kill-line

ACTION COMPOSITION
Multiple actions can be chained using + separator.
e.g.
fzf --multi --bind 'ctrl-a:select-all+accept'
fzf --multi --bind 'ctrl-a:select-all' --bind 'ctrl-a:+accept'
ACTION ARGUMENT
An action denoted with (...) suffix takes an argument.
e.g.
fzf --bind 'ctrl-a:change-prompt(NewPrompt> )'
fzf --bind 'ctrl-v:preview(cat {})' --preview-window hidden
If the argument contains parentheses, fzf may fail to parse the expression. In that case, you can use any of the following alternative notations to avoid parse errors.
action-name[...]
action-name~...~
action-name!...!
action-name@...@
action-name#...#
action-name$...$
action-name%...%
action-name^...^
action-name&...&
action-name*...*
action-name;...;
action-name/.../
action-name|...|
action-name:...
The last one is the special form that frees you from parse errors as it does not expect the closing character. The catch is that it should be the last one in the comma-separated
list of key-action pairs.
COMMAND EXECUTION
With execute(...) action, you can execute arbitrary commands without leaving fzf. For example, you can turn fzf into a simple file browser by binding enter key to less command like
follows.
fzf --bind "enter:execute(less {})"
You can use the same placeholder expressions as in --preview.
fzf switches to the alternate screen when executing a command. However, if the command is expected to complete quickly, and you are not interested in its output, you might want to use
execute-silent instead, which silently executes the command without the switching. Note that fzf will not be responsive until the command is complete. For asynchronous execution, start
your command as a background process (i.e. appending &).
On *nix systems, fzf runs the command with $SHELL -c if SHELL is set, otherwise with sh -c, so in this case make sure that the command is POSIX-compliant.
RELOAD INPUT
reload(...) action is used to dynamically update the input list without restarting fzf. It takes the same command template with placeholder expressions as execute(...).
See https://github.com/junegunn/fzf/issues/1750 for more info.
e.g.
# Update the list of processes by pressing CTRL-R
ps -ef | fzf --bind 'ctrl-r:reload(ps -ef)' --header 'Press CTRL-R to reload' \
--header-lines=1 --layout=reverse
# Integration with ripgrep
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="foobar"
FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \
fzf --bind "change:reload:$RG_PREFIX {q} || true" \
--ansi --disabled --query "$INITIAL_QUERY"
PREVIEW BINDING
With preview(...) action, you can specify multiple different preview commands in addition to the default preview command given by --preview option.
e.g.
# Default preview command with an extra preview binding
fzf --preview 'file {}' --bind '?:preview:cat {}'
# A preview binding with no default preview command
# (Preview window is initially empty)
fzf --bind '?:preview:cat {}'
# Preview window hidden by default, it appears when you first hit '?'
fzf --bind '?:preview:cat {}' --preview-window hidden
CHANGE PREVIEW WINDOW ATTRIBUTES
change-preview-window action can be used to change the properties of the preview window. Unlike the --preview-window option, you can specify multiple sets of options separated by '|'
characters.
e.g.
# Rotate through the options using CTRL-/
fzf --preview 'cat {}' --bind 'ctrl-/:change-preview-window(right,70%|down,40%,border-horizontal|hidden|right)'
# The default properties given by `--preview-window` are inherited, so an empty string in the list is interpreted as the default
fzf --preview 'cat {}' --preview-window 'right,40%,border-left' --bind 'ctrl-/:change-preview-window(70%|down,border-top|hidden|)'
# This is equivalent to toggle-preview action
fzf --preview 'cat {}' --bind 'ctrl-/:change-preview-window(hidden|)'
