SYNOPSIS

       head [OPTION]... [FILE]...

DESCRIPTION

       Print  first  10 lines of each FILE to standard output.	With more than one FILE, precede each with a header giving the file name.  With no

       Mandatory arguments to long options are mandatory for short options too.

       -c, --bytes=SIZE
	      print first SIZE bytes

       -n, --lines=NUMBER
	      print first NUMBER lines instead of first 10

       -q, --quiet, --silent
	      never print headers giving file names

       -v, --verbose
	      always print headers giving file names

       --help display this help and exit

       --version
	      output version information and exit

       SIZE may have a multiplier suffix: b for 512, k for 1K, m for 1 Meg.
