NAME
       head - display first few lines of files

SYNOPSIS
       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 will look 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 will be copied to standard output. The number option-argument must be a  positive
		       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 will act as if -n 10had been specified.

OPERANDS
       The following operand is supported:

       file	       A path name of an input file. If no file operands are specified, the standard input will be used.

USAGE
       See largefile(5) for the description of the behavior of head when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

EXAMPLES
       Example 1: Writing the first ten lines of all files

       To write the first ten lines of all files (except those with a leading period) in the directory:

       example% head *
