DESCRIPTION

       This  manual page documents the GNU version of head.  head
       prints the first part (10 lines by default) of each  given
       file;  it  reads from standard input if no files are given
       or when a filename of `-' is encountered.   If  more  than
       one  file  is  given, it prints a header consisting of the
       file's name enclosed in `==>' and `<==' before the  output
       for each file.

   OPTIONS
       head  accepts  two  option  formats: the new one, in which
       numbers are arguments to the option letters, and  the  old
       one, in which the number precedes any option letters.

       -c N, --bytes N
              Print  first  N  bytes.   N  is  a nonzero integer,
              optionally followed by one of the following charac-
              ters to specify a different unit.

              b      512-byte blocks.

              k      1-kilobyte blocks.

       -n N, --lines N
              Print first N lines.

       -q, --quiet, --silent
              Never print filename headers.

       -v, --verbose
              Always print filename headers.

       --help Print  a  usage message and exit with a status code
              indicating success.
