OPTIONS ------- .. option:: -z, --compress Compress the file .. option:: -d, --decompress Decompress the file .. option:: -k, --keep Keep the input file. .. option:: -f, --force Overwrite the output file, if it exists. .. option:: -b, --blocksize SIZE Set the compression block size, from 1 to 9. Where 1=100kB ... and 9=900kB. Default is 9. .. option:: -v, --verbose Verbose output (optional). .. option:: -q, --quiet Quiet output .. option:: -h, --help Print usage. EXAMPLES -------- 1. To compress a file: ``mpirun -np 128 dbz2 --compress /path/to/file`` 2. To compress a file and overwrite any existing output file: ``mpirun -np 128 dbz2 --force --compress /path/to/file`` 3. To decompress a file: ``mpirun -np 128 dbz2 --decompress /path/to/file.dbz2`` SEE ALSO -------- The mpiFileUtils source code and all documentation may be downloaded from
