usage:
|
|
rsync <script options> source destination <rsync options> --- <ssh options>
|
|
|
|
Available Script Options
|
|
-r, run the command by this script uses --dry-run. When ready pass this flag.
|
|
-s, run command as sudo
|
|
-l, list the rsync command that will be run instead of running it. removes --dry-run.
|
|
great for generating a rsync command to be used elsewhere
|
|
-p, make path at destination if need be. careful will creating missing subdirectories
|
|
-e, rsync --exclude , as many of these as desired
|
|
-i, insert source inside destination instead of making folder at destination, good for changing destination folder name
|
|
-m, copy as "mirror" uses options. -a --numeric-ids --delete --force
|
|
-M, copy as "mirror" above -m plus '--delete-excluded' added. A perfect mirror
|
|
-f, rsync --exclude-from <path>, can have multiple
|
|
-F, copy a filesystem, uses -M mirror plus -xHAXS, and uses sudo (i.e. -s script option)
|
|
-n, no confirm, will always confirm command unless this is set
|
|
-q, quiet, suppress progress
|
|
-v, verbose, same as -v for rsync option, unset if -q is set
|
|
-a, archive, same as -a for rsync option, basic identical copy with recursion
|
|
-c, clean tranfer meaning will not transfer folder with trash, cache, log, nodemodules
|
|
-C, show excludes for clean transfer
|
|
-h, this help text
|
|
|
|
source or destination may include a <host>: prefix but not both
|
|
|
|
use 'fcopy <src> <dest>' for fast copy uses -r -q -m -n -a
