SYNOPSIS
# Rebuild the source cache for rapid updating.
dirsync [ options ] --rebuild <source_dir>
# Quickly update source to destination.
dirsync [ options ] <source_dir> <dest_dir>
-or-
# Mirror source to destination ignoring cache.
# (almost like: cp -a <source_dir>/. <dest_dir>/.
# except files may be deleted in destination
# to ensure exact consistency with source.)
dirsync [ options ] --nocache <source_dir> <dest_dir>
DESCRIPTION
This is just a wrapper script for easy commandline access to
File::DirSync. It mirrors all files and symlinks recursively from
source_dir to dest_dir.
OPTIONS--help (or -h)
Show this help screen
--rebuild (or -r)
Rebuilds the dirsync cache on source_dir. Write access to source_dir
is required to rebuild. If dest_dir is not specified when this option
is, then nothing is mirrored to anywhere after the cache is rebuilt.
--local (or -l)
Local directory only, no recursion.
--nocache (or -n)
When mirroring from source_dir to dest_dir, do not assume that
--rebuild has built the dirsync cache on source_dir already. It is
ignored and all files are mirrored. This option will significantly
slow the performance of the mirroring process.
--ignore <dir> (or -i=<dir>)
Avoid recursing into directories named <dir> within the entire descent
of source_dir. This option applies to both the --rebuild option and
the mirroring process if a second directory is supplied. It may be
specified multiple times to ignore several directories.
--only <node> (or -o=<node>)
If this option is used, this will be the only node checked for changes,
but the cache will still be rebuilt all the way to source_dir. This
only node must always be a subdirectory or a file within a subdirectory
of source_dir. This option only applies to the --rebuild option. It
may be specified multiple times to rebuild several nodes.
--skew (or -s)
Enable clock skew protection. If a file or directory is found within
source_dir modified in the future, the timestamp will be reset back to
"now" to prevent corrupting the directory cache into the future.
--concur <lockfile> (or -c=<lockfile>)
If this option is used, <lockfile> will be used to ensure that only one
dirsync process is running at a time. If another process is
concurrently running, this process will immediately abort without doing
anything. If <lockfile> does not exist, it will be created.
--gentle <percent>[:<ops>] (or -g=<percent>:<ops>)
If this option is specified, then dirsync will spend <percent> % of the
time sleeping instead of syncing. If <ops> is specified, it will
perform <ops> disk operations in between each pause cycle. If this
option is not specified, dirsync will burn continually until the
process has completed.
--proctitle (or -p)
If this option is specified, the process name will be modified to show
the current operation. This can be useful for viewing or monitoring
the progress.
--verbose (or -v)
Show extra details.
