rsync is a tool which is used top synch two directory structures on local or remote filesystems.
Generally used like:
rsync <source> <destination>
Generic Args + Dry Runs
I often create an rsync command like
rsync -nvrculzOFF source_directory/* [email protected]:path/to/files
The first flag
-n forces a try run (alt:
--dry-run) so you quickly have to follow it up with:
rsync -vrculzOFF source_directory/* [email protected]:path/to/files
to run the command and actually do the sync.
The remaining flags are as follows
-v: Verbose output
-r: Recursive sync
-c: Checksum, Skip files based on checkum, not mod-time & size
-u: Update, Skip files that are newer on the receiver
-l: Copy symlinks as symlinks
-zOFF: Compression off
This is just a handy one I have memorized over the years. Be sure to
man rsync for more options.
Files that match a patter can be excluded as follows
--exclude=PATTERN: exclude files matching PATTERN
--exclude-from=FILE: read exclude patterns from FILE
