     COMPRESS(C)              XENIX System V               COMPRESS(C)



     Name
          compress - compress data for storage.
          uncompress - uncompress a stored file.
          zcat - display a stored file.

     Syntax
          compress [-dfFqc] [-b bits] file
          uncompress [-fqc] file
          zcat file

     Description
          compress takes a file and compresses it to the smallest
          possible size, creates a compressed output file, and removes
          the original file unless the -c option is present.
          Compression is achieved by encoding common strings within
          the file. uncompress restores a previously compressed file
          to its uncompressed state and removes the compressed
          version. zcat uncompresses and displays a file on the
          standard output. When zcat is used to display a file, the
          file is uncompressed and concatenated on the screen or
          standard output, and the compressed version of the file is
          not removed.

          If no file is specified on the command line, input is taken
          from the standard input and the output is directed to the
          standard output. Output defaults to a file with the same
          filename as the input file with the suffix ``.Z'' or it can
          be directed through the standard output. The output files
          have the same permissions and ownership as the corresponding
          input files or the user's standard permissions if output is
          directed through the standard output.

          If no space is saved by compression, the output file is not
          written unless the -F flag is present on the command line.

     Options
          The following options are available from the command line:

          -d       Decompresses a compressed file.

          -c       Writes output on the standard output and does not
                   remove original file.

          -bbits   Specifies the maximum number of bits to use in
                   encoding.

          -f       Overwrites previous output file.

          -F       Writes output file even if compression saves no
                   space.

          -q       Generates no output except error messages, if any.
