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.

       If  any	internationalization  variable	contains an invalid setting, 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 bytes.

NAME

       uniq - report repeated lines in a file

SYNOPSIS

       fields] chars] [input_file [output_file]]

DESCRIPTION

       reads  the input text file input_file, comparing adjacent lines, and copies the result to output_file.  If input_file is not specified, the
       standard input and standard output are used.  If input_file is specified, but output_file is not, results are printed to  standard  output.
       input_file and output_file must not be the same file.

   Line-Comparison Options
       recognizes the following options when comparing adjacent lines:

	      Print   those lines that are repeated in the original file.

	      Print   copy only of each repeated line in the input file.

	      Generate an output report in default style
		      except  that  each  line	is  preceded  by a count of the number of times it occurred.  If this option is specified, the and
		      options are ignored if either or both are also present.

       If none of the options or are present, prints the results of the union of the and options, producing a copy of the original input file with
       the  second  and  succeeding  copies of any repeated lines removed.  (Note that repeated lines must be adjacent in order to be found -- see
       sort(1)).

   Field-Skip Options
       Two options are provided for skipping an initial portion of each line when making comparisons:

	      Ignore the first
			     fields fields, together with any blanks before each.  fields is a positive decimal integer.  A field is defined as  a
			     string of non-space, non-tab characters separated by tabs and/or spaces from its neighbors.

	      Ignore the first
			     chars  characters.   chars  is a positive decimal integer.  Each line in the input is assumed to be terminated with a
			     new line character for purposes of comparison.  Fields are skipped before characters.

EXTERNAL INFLUENCES

   Environment Variables
       must be equal to the value it had when the input files were sorted.

       determines the interpretation of text within files as single- and/or multi-byte characters, and defines	a  space  character  when  the	or
       option is used.

       determines the language in which messages are displayed.

       If  or  is  not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty
       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 environ(5).

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

RETURN VALUE

       Exit values are:

	       0      Successful completion.
	      >0      Error condition occurred.
