watchexec 1.16.0
Execute commands when watched files change
USAGE:
watchexec [FLAGS] [OPTIONS] <command>...
FLAGS:
--changes-only Only print path change information. Overridden by --verbose
-c, --clear Clear screen before executing command
-h, --help Prints help information
--no-default-ignore Skip auto-ignoring of commonly ignored globs
--no-environment Do not set WATCHEXEC_*_PATH environment variables for the command
--no-ignore Skip auto-loading of ignore files (.gitignore, .ignore, etc.) for filtering
--no-meta Ignore metadata changes
-n, --no-shell Do not wrap command in a shell. Deprecated: use --shell=none instead.
--no-vcs-ignore Skip auto-loading of .gitignore files for filtering
-p, --postpone Wait until first change to execute command
-r, --restart Restart the process if it's still running. Shorthand for --on-busy-update=restart
-V, --version Prints version information
-v, --verbose Print debugging messages to stderr
-W, --watch-when-idle Deprecated alias for --on-busy-update=do-nothing, which will become the default in 2.0.
OPTIONS:
-d, --debounce <milliseconds> Set the timeout between detected change and command execution, defaults to
150ms
-e, --exts <extensions> Comma-separated list of file extensions to watch (e.g. js,css,html)
-f, --filter <pattern>... Ignore all modifications except those matching the pattern
-i, --ignore <pattern>... Ignore modifications to paths matching the pattern
--on-busy-update <on-busy-update> Select the behaviour to use when receiving events while the command is
running. Current default is queue, will change to do-nothing in 2.0.
[possible values: do-nothing, queue, restart, signal]
-w, --watch <path>... Watch a specific file or directory
--force-poll <interval> Force polling mode (interval in milliseconds)
--shell <shell> Use a different shell, or `none`. E.g. --shell=bash
-s, --signal <signal> Send signal to process upon changes, e.g. SIGHUP
ARGS:
<command>... Command to execute
