dsync ===== SYNOPSIS -------- **dsync [OPTION] SRC DEST** DESCRIPTION ----------- Parallel MPI application to synchronize two files or two directory trees. dsync makes DEST match SRC, adding missing entries from DEST, and updating existing entries in DEST as necessary so that SRC and DEST have identical content, ownership, timestamps, and permissions. OPTIONS ------- .. option:: --dryrun Show differences without changing anything. .. option:: -b, --batch-files N Batch files into groups of up to size N during copy operation. .. option:: -c, --contents Compare files byte-by-byte rather than checking size and mtime to determine whether file contents are different. .. option:: -D, --delete 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:: -q, --quiet Run tool silently. No output is printed. .. option:: -h, --help Print the command usage, and the list of options available. EXAMPLES -------- 1. Synchronize dir2 to match dir1: ``mpirun -np 128 dsync /path/to/dir1 /path/to/dir2`` SEE ALSO -------- The mpiFileUtils source code and all documentation may be downloaded from
