NAME
|
|
----
|
|
lsyncd - a daemon to continuously synchronize directory trees
|
|
|
|
SYNOPSIS
|
|
--------
|
|
config file:::
|
|
{nbsp} *lsyncd* ['OPTIONS'] 'CONFIG-FILE'
|
|
|
|
default rsync behaviour:::
|
|
{nbsp} *lsyncd* ['OPTIONS'] -rsync 'SOURCEDIR' 'TARGET' ...
|
|
|
|
default rync+ssh behaviour (moves and deletes through ssh):::
|
|
{nbsp} *lsyncd* ['OPTIONS'] -rsyncssh 'SOURCEDIR' 'TARGETHOST' 'TARGETDIR' ...
|
|
|
|
default direct behaviour (local file operations/rsync):::
|
|
{nbsp} *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://lsyncd.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.
|
|
|

|
|
*-onepass*::
|
|
Sync once and exit
|

*-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*::

|
|
EXIT STATUS
|
