dsync [OPTION] SRC DEST
Parallel MPI application to synchronize two files or two directory trees.
dsync makes DEST match SRC, adding missing entries from DEST, removing extra entries from DEST, and updating existing entries in DEST as necessary so that SRC and DEST have identical content, ownership, timestamps, and permissions.
.. option:: --dryrun
Show differences without changing anything.
.. option:: -c, --contents
Compare files byte-by-byte rather than checking size and mtime
to determine whether file contents are different.
.. option:: -N, --no-delete
Do not delete extraneous files from destination.
.. option:: -v, --verbose
Run in verbose mode. Prints a list of statistics/timing data for the
command. Files walked, started, completed, seconds, files, bytes
read, byte rate, and file rate.
.. option:: -h, --help
Print the command usage, and the list of options available.
- Synchronize dir2 to match dir1:
mpirun -np 128 dsync /path/to/dir1 /path/to/dir2
