USAGE
compress [-dfvc] [-b maxbits] [file ...]
DESCRIPTION
Compress uses Modified Lempel-Ziv-Welch compression to compress
the named input files (or standard input if none are specified).
Each named file is compressed, then, if the compression results in a
smaller file, the compressed file replaces the original file. The
compressed filename is the original with the suffix .Z. Using the
-d option, the specified files (or standard input if none are specified)
will be decompressed, and the decompressed file will replace the
compressed version.
OPTIONS
-d Decompress the specified files.
-c send all output to standard out.
In particular, compress -dc will decompress the file
and send the result to standard out without deleting the
original file, providing a way to list a compressed file
directly.
-f Force the output file to be generated, even if no savings
result.
-v Write compression statistics.
-b maxbits Set the maximum number of bits/code. Generally, more bits
will result in better compression.
