 head(1)                                                             head(1)




 NAME
      head - give first few lines

 SYNOPSIS
      head [-c|-l] [-n count] [file ...]

    Obsolescent:
      head [-count] [file ...]

 DESCRIPTION
      head prints on standard output the first count lines of each of the
      specified files, or of the standard input.  If count is omitted it
      defaults to 10.

      If multiple files are specified, head outputs before each file a line
      of this form:

           ==>&gt&gt&gt; file <&lt&lt&lt;==

    Options
      -c             The quantity of output is measured in bytes.

      -count         The number of units of output.  This option is provided
                     for backward compatibility (see -n below) and is
                     mutually exclusive of all other options.

      -l             The quantity of output is measured in lines; this is
                     the default.

      -n count       The number of lines (default) or bytes output.  count
                     is an unsigned decimal integer.  If -n (or -count) is
                     not given, the default quantity is 10.  This option
                     provides the same functionality as the -count option,
                     but in a more standard way.  Use of the -n option is
                     recommended where portability between systems is
                     important.

 EXTERNAL INFLUENCES
    Environment Variables
      LC_CTYPE determines the interpretation of text within file as single
      and/or multi-byte characters.

      LC_MESSAGES determines the language in which messages are displayed.

      If LC_CTYPE or LC_MESSAGES is not specified in the environment or is
      set to the empty string, the value of LANG is used as a default for
      each unspecified or empty variable.  If LANG is not specified or is
      set to the empty string, a default of "C" (see lang(5)) is used
      instead of LANG.

      If any internationalization variable contains an invalid setting, head
      behaves as if all internationalization variables are set to "C".  See
      environ(5).

    International Code Set Support
      Single- and multi-byte character code sets are supported.

 WARNINGS
      The length of the input lines is limited to {LINE_MAX} bytes.
