NAME

       git-fsmonitor--daemon - A Built-in Filesystem Monitor

SYNOPSIS

       git fsmonitor--daemon start
       git fsmonitor--daemon run
       git fsmonitor--daemon stop
       git fsmonitor--daemon status

DESCRIPTION

       A daemon to watch the working directory for file and directory changes using
       platform-specific filesystem notification facilities.

       This daemon communicates directly with commands like git status using the simple IPC[1]
       interface instead of the slower githooks(5) interface.

       This daemon is built into Git so that no third-party tools are required.

OPTIONS

       start
           Starts a daemon in the background.

       run
           Runs a daemon in the foreground.

       stop
           Stops the daemon running in the current working directory, if present.

       status
           Exits with zero status if a daemon is watching the current working directory.

REMARKS

       This daemon is a long running process used to watch a single working directory and
       maintain a list of the recently changed files and directories. Performance of commands
       such as git status can be increased if they just ask for a summary of changes to the
       working directory and can avoid scanning the disk.

       When core.fsmonitor is set to true (see git-config(1)) commands, such as git status, will
       ask the daemon for changes and automatically start it (if necessary).

       For more information see the "File System Monitor" section in git-update-index(1).

CAVEATS

       The fsmonitor daemon does not currently know about submodules and does not know to filter
       out filesystem events that happen within a submodule. If fsmonitor daemon is watching a
       super repo and a file is modified within the working directory of a submodule, it will
       report the change (as happening against the super repo). However, the client will properly
       ignore these extra events, so performance may be affected but it will not cause an
       incorrect result.

       By default, the fsmonitor daemon refuses to work against network-mounted repositories;
       this may be overridden by setting fsmonitor.allowRemote to true. Note, however, that the
       fsmonitor daemon is not guaranteed to work correctly with all network-mounted repositories
       and such use is considered experimental.

       On Mac OS, the inter-process communication (IPC) between various Git commands and the
       fsmonitor daemon is done via a Unix domain socket (UDS) — a special type of file — which
       is supported by native Mac OS filesystems, but not on network-mounted filesystems, NTFS,
       or FAT32. Other filesystems may or may not have the needed support; the fsmonitor daemon
       is not guaranteed to work with these filesystems and such use is considered experimental.

       By default, the socket is created in the .git directory, however, if the .git directory is
       on a network-mounted filesystem, it will be instead be created at $HOME/.git-fsmonitor-*
       unless $HOME itself is on a network-mounted filesystem in which case you must set the
       configuration variable fsmonitor.socketDir to the path of a directory on a Mac OS native
       filesystem in which to create the socket file.

       If none of the above directories (.git, $HOME, or fsmonitor.socketDir) is on a native Mac
       OS file filesystem the fsmonitor daemon will report an error that will cause the daemon
       and the currently running command to exit.

CONFIGURATION

       Everything below this line in this section is selectively included from the git-config(1)
       documentation. The content is the same as what’s found there:

       fsmonitor.allowRemote
           By default, the fsmonitor daemon refuses to work against network-mounted repositories.
           Setting fsmonitor.allowRemote to true overrides this behavior. Only respected when
           core.fsmonitor is set to true.

       fsmonitor.socketDir
           This Mac OS-specific option, if set, specifies the directory in which to create the
           Unix domain socket used for communication between the fsmonitor daemon and various Git
           commands. The directory must reside on a native Mac OS filesystem. Only respected when
           core.fsmonitor is set to true.
