Recursively monitors directories for changes, executing the command when a filesystem change (add/modify/delete) is detected. By default, watchexec uses efficient kernel-level mechanisms to watch for changes.
At startup, the specified <command> (passing any supplied <argument>s) is run once, and watchexec begins monitoring for changes.
Specifies the path to watch. This argument can be specified multiple times, with all paths being watched simultaneously. Defaults to current directory.
* `-e`, `--exts` <extensions>:
Comma-separated list of file extensions to filter by. Leading dots are allowed (.rs) are allowed. (This is a shorthand for `-f`).
Ignores modifications from paths that do not match <pattern>. This option can be specified multiple times, where a match on any given pattern causes the path to trigger *command*.
Ignores modifications from paths that match <pattern>. This option can be specified multiple times, and a match on any pattern causes the path to be ignored.
* `-r`, `--restart`:
Sends SIGTERM to the child process if it is still running when subsequent file modifications are detected, then waits for the child to exit.
* `-c`, `--clear`:
Clears the screen before executing <command>.
* `-p`, `--postpone`:
Postpone execution of <command> until the first file modification is detected.
* `-d`, `--debug`:
Prints diagnostic messages to STDERR
* `--force-poll` <interval>:
When watching directories, poll for changes every <interval> ms instead of using system-specific notification mechanisms (such as inotify). This is useful when you are monitoring NFS shares.
* `--no-vcs-ignore`:
Skip loading of version control system (VCS) ignore files. By default, watchexec loads .gitignore files in the current directory (or parent directories) and uses them to populate the ignore list.
Processes started by watchexec have the `$WATCHEXEC_UPDATED_PATH` environment variable set to the path of the first modification observed. In addition, the `$WATCHEXEC_COMMON_PATH` environment variable is set to the common path of all observed modifications.
