  6. Name

"lrsync" means "live rsync".

  1. Motivation

To make clsync more convenient and useful.

Well, honestly, this's quite useless utility because you can work with clsync directly :)

  1. How does that work

"lrsync" just parses arguments and sorts it for clsync and rsync (via clsync's "sync-handler-arguments"), after that it calls clsync this way: clsync -Klrsync -Mrsyncdirect -S path_to_rsync -W source_directory -D destination_directory -L /tmp/.lrsync clsync_arguments -- %RSYNC-ARGS% rsync_arguments. In this command clsync_arguments, rsync_arguments, source_directory and destination_directory are parsed from lrsync arguments.

You can see the result clsync command using option "--clsync-command-only". For example:

$ lrsync --exit-on-no-events --max-iterations=20 -av 1/ 2/ --clsync-command-only
clsync \
  -Klrsync \
  -Mrsyncdirect \
  -S \
  rsync \
  -W \
  1/ \
  -D \
  2/ \
  -L \
  /tmp/.lrsync \
  --exit-on-no-events \
  --max-iterations=20 \
  -- \
  %RSYNC-ARGS% \
  -av \
  1/ \
  2/
  1. Use cases

  1. This may be useful if you have a directory that is actively updated. And you want to move it somewhere. You can just call:

    lrsync --exit-hook /root/apacherestart.sh --exit-on-no-events --max-iterations 20 --inplace -av /usr/www/ /var/www/

  2. You want to get two directories in synchronous state:

    lrsync --delay-sync 3 --delay-collect 3 --delay-collect-bigfile 3 -av /home/dir1 /home/dir2
