head(1)                          User Commands                         head(1)



NAME
       head - display first few lines of files

SYNOPSIS
       /usr/bin/head [-number | -n number] [filename]...

DESCRIPTION
       The  head  utility copies the first number of lines of each filename to
       the standard output. If no filename is given, head  copies  lines  from
       the standard input. The default value of number is 10 lines.


       When  more  than  one  file  is specified, the start of each file looks
       like:

         ==> filename <==



       Thus, a common way to display a set of short  files,  identifying  each
       one, is:

         example% head -9999 filename1 filename2 ...


OPTIONS
       The following options are supported:

       -n number    The  first  number  lines  of each input file is copied to
                    standard output. The number option-argument must be a pos‐
                    itive decimal integer.


       -number      The number argument is a positive decimal integer with the
                    same effect as the -n  number option.



       If no options are specified, head acts as if -n  10 had been specified.

OPERANDS
       The following operand is supported:

       filename    A path name of an input file. If no file operands are spec‐
                   ified, the standard input is used.


EXAMPLES
       Example 1 Writing the First Ten Lines of All Files



       The  following  example writes the first ten lines of all files, except
       those with a leading period, in the directory:


         example% head *
