NAME

       head - give first few lines

SYNOPSIS

       count] [file ...]

   Obsolescent:
       [file ...]

DESCRIPTION

       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, outputs before each file a line of this form:

	      file

   Options
       The quantity of output is measured in bytes.

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

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

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

       variable.  If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of

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