GZIP(1)                                                   GZIP(1)

     NAME
          gzip, gunzip - compression and decompression utilities

     SYNOPSIS
          gzip [ -v ] [ -level ] [ file... ]
          gunzip [ file... ]

     DESCRIPTION
          Gzip and gunzip perform data compression and decompression
          compatible with the Unix gzip file format, which uses a
          hybrid Lempel-Ziv 1977 and Huffman compression algorithm
          called `deflate'.  If no arguments are given gzip compresses
          each file replacing it by a file of the same name with the a
          .gz suffix appended.  If no files are given, standard input
          and standard output are used.  Level is a single decimal
          digit between 1 and 9; higher numbers give better compres-
          sion.  The default level is 6.  The -v option causes gzip to
          report the compression ratio of each file that it com-
          presses.

          Gunzip performs the opposite operation to gzip; each file
          (which must have a .gz suffix) is uncompressed, and replaced
          by a file of the same name with the .gz suffix removed. If
          no files are given, standard input and standard output are
          used.
