NAME

       lsyncd - a daemon to continuously synchronize directory trees

SYNOPSIS

       config file
             lsyncd [OPTIONS] CONFIG-FILE

       default rsync behaviour
             lsyncd [OPTIONS] -rsync SOURCEDIR TARGET ...

       default rync+ssh behaviour (moves and deletes through ssh)
             lsyncd [OPTIONS] -rsyncssh SOURCEDIR TARGETHOST TARGETDIR ...

       default direct behaviour (local file operations/rsync)
             lsyncd [OPTIONS] -direct SOURCEDIR TARGETDIR ...

DESCRIPTION

       Lsyncd(1) watches local directory trees through an event monitor interface (inotify, fsevents). It
       aggregates and combines events for a few seconds and then spawns one or more processes to synchronize the
       changes. By default this is rsync(1). Lsyncd is thus a light-weight asynchronous live mirror solution
       that is comparatively easy to install not requiring new filesystems or block devices and does not hamper
       local filesystem performance.

       Rsync+ssh is an advanced action configuration that uses a SSH(1) to act file and directory moves directly
       on the target instead of re-transmitting the move destination over the wire.

       Fine-grained customization can be achieved through the CONFIG-FILE. Custom action configs can even be
       written from scratch in cascading layers ranging from shell scripts to code written in the LUA(1)
       language. This way simplicity can be balanced with powerfulness. See the online manual for details on the
       CONFIG-FILE https://axkibe.github.io/lsyncd/manual/config/file/ .

       Note that under normal configuration Lsyncd will delete pre-existing files in the target directories that
       are not present in the respective source directory.

OPTIONS

       -delay SECS
           Overrides the default delay times.

       -help
           Show a help message.

       -insist
           Continues start up even if rsync cannot connect.

       -log LEVEL
           Controls which kind of events are logged. By default Lsyncd logs Normal and Error Messages.  -log
           scarce will make Lsyncd log Error messages only.  -log all will log all debug messages.

       -log Category
           Turns on a specific debug message. E.g.  -log Exec will log all processes as they are spawned.

       -nodaemon
           Lsyncd will not detach from the invoker and log as well to stdout/err.

       -pidfile FILE
           Lsyncd will write its process ID in FILE.

       -runner FILE
           Makes the Lsyncd core load the part of Lsyncd written in Lua from FILE.

       -version
           Writes version information and exits.

EXIT STATUS

       (128+SIGNUM)
           Terminated by Signal (143 by TERM)

       -1
           Failure (syntax, unrecoverable error condition, internal failure)
