NAME
head - display opening lines of files
SYNOPSIS
head [-n number] [--] [file ...]
DESCRIPTION
head copies the opening lines of a file to standard output. If no file
is given, head reads from standard input.
OPTIONS
-n number
Number of lines to be output.
-n not specified: The first 10 lines are output.
-n number is equivalent to the old -number option, which will
continue to be supported.
-- If file begins with a dash (-), the end of the command-line
options must be marked with --.
file Name of the input file. If more than one file is named, the files
will be processed in the order in which they are listed, and the
output of each file begins with: ==>file<==.
LOCALE
The LCMESSAGES environment variable governs the language in which
message texts are displayed. If LCMESSAGES is undefined or is defined
as the null string, it defaults to the value of LANG. If LANG is like-
wise undefined or null, the system acts as if it were not internation-
alized.
The LCALL environment variable governs the entire locale. LCALL
takes precedence over all the other environment variables which affect
internationalization.
EXAMPLES
To see the first 5 lines of three files, you enter the head command as
shown below:
$ head -n 5 file1 file2 file3
The first five lines of each of the three files are written to stan-
dard output as follows:
==>file1<==
Lines 1-5 of file 1
==>file2<==
Lines 1-5 of file 2
