to-bzip(1)                                                          to-bzip(1)




NAME

       to-bzip - converts .Z, .lzo, .zip, .rar, and .gz files to bzip2 format


SYNOPSIS

       to-bzip     [-(IPv)4]    [-(IPv)6]    [-d(elete_original)]    [-h(elp)]
       [-k(eep_smallest)]   [-n(o_overwrite)]   [-p    num_cores]    [-t(imes-
       tamp_retain)] file/URL...


DESCRIPTION

       to-bzip  recompresses  files  compressed  with the compress, lzop, zip,
       and/or gzip utilities into bzip2 format.  The  newly  compressed  files
       will  usually  have a .bz2 or a .tbz extension.  If a specified file is
       actually a URL, it will be downloaded using wget and then recompressed.


OPTIONS

       -4     Prefer IPv4 when downloading a URL.

       -6     Prefer IPv6 when downloading a URL.

       -d     After each file is compressed, delete the original.

       -h     Print help and quit.

       -k     Once  a  file is successfully recompressed, delete the larger of
              the original file or the new one.  This  option  maximizes  disk
              space savings and is incompatible with the -d option.

       -n     Do  not  overwrite  the  target  .bz2 or .tbz file if it already
              exists.

       -p num_cores
              Use multi-threaded lbzip2 or pbzip2 instead of bzip2 to  utilize
              multiple  cores  during compression.  Note that the output file,
              while being fully  compatible  with  bzip2,  will  generally  be
              slightly larger.  Specifying a num_cores value of zero will uti-
              lize all available cores.

       -t     Make the timestamp of new files match those of the old files.
