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.
