lsyncd

a daemon to continuously synchronize directory trees



config file lsyncd [OPTIONS] CONFIG-FILEdefault 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 ...



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 blockdevices 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 retransmitting 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 http://code.google.com/p/lsyncd/wiki/Lsyncd20Manual

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



-delay SECS Overrides the default delay times.-help Show a help message.-insist Continues startup even if a startup rsync cannot connect.-log 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 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 Lsyncd will write its process ID in FILE.-runner Makes the Lsyncd core load the part of Lsyncd written in Lua from FILE.-version Writes version information and exits.



0 Terminated on a TERM signal(7)-1 Failure (syntax, unrecoverable error condition, internal failure)
