  pr - Writes a	file to	standard output


  pr [-adfFmprt] [-e] [character] [number] [-h header] [-i] [character]	[gap]
  [-l lines] [-n] [character] [width] |	[-x] [character] [number] [-o offset]
  [-s] [character] [-w width] [-column]	[+page]	[file...]

  The pr command writes	file to	standard output.  If you do not	specify	file
  or if	file is	-, pr reads standard input.


  Interfaces documented	on this	reference page conform to industry standards
  as follows:

  pr:  XCU5.0

  Refer	to the standards(5) reference page for more information	about indus-
  try standards	and associated tags.


  -a  Displays multicolumn output across the page.  (This option is meaning-
      ful only in combination with the -column option.	It modifies -column
      so that columns are filled across	the page in a round robin order.)

  -d  Doublespaces the output.

      Expands tabs to byte positions number+1, 2*number+1, 3*number+1, and so
      on.  The default value of	number is 8.  Tab characters in	the input
      expand to	the appropriate	number of spaces to line up with the next tab
      setting.	If you specify character (any character	other than a digit)
      that character becomes the input tab character.  The default value of
      character	is the ASCII tab character.

  -f  Uses a formfeed character	to advance to a	new page. (Otherwise, pr
      issues a sequence	of newline characters.)	 Pauses	before beginning the
      first page if the	standard output	is a terminal.

  -F  Uses a formfeed character	to advance to a	new page. (Otherwise, pr
      issues a sequence	of newline characters.)	 Does not pause	before begin-
      ning the first page if the standard output is a terminal.

  -h header
      Displays header instead of the file name in the page header.

      Replaces multiple	space characters with tab characters wherever two or
      more space characters reach positions gap+1, 2*gap+1, 3*gap+1, and so
      on.  The default value of	gap is 8.  If you specify character (any
      character	other than a digit), that character becomes the	output tab
      character.  (The default value of	character is the ASCII tab charac-

  -l lines
      Sets the length of a page	to lines lines (the default is 66).  If	lines
      is not greater than the sum of the header	and trailer, pr	suppresses
      both header and trailer, as if -t	were in	effect.

  -m  Combines and writes all files at the same	time, with each	file in	a
      separate column.	(This overrides	the -column and	-a options).

      Provides width-digit line	numbering (the default value of	width is 5).
      The number occupies the first width positions of each column of normal
      output (or each line of -m output).  If you specify character (any
      character, other than a digit), that character is	added to the line
      number to	separate it from whatever follows.  (The default value of
      character	is an ASCII tab	character.)

  -o offset
      Indents each line	of output by offset byte positions (the	default	is
      0).  This	is in addition to output width (see -w).

  -p  Pauses before beginning each page	if the output is directed to a termi-
      nal.  (pr	sounds the bell	at the terminal	and waits for you to press

  -r  Does not display diagnostic messages if the system cannot	open files.

      Separates	columns	by the single character	instead	of by the appropriate
      number of	spaces (the default for	character is an	ASCII tab character).

  -t  Does not display the 5-line identifying header and the 5-line footer.
      Stops after the last line	of each	file without spacing to	the end	of
      the page.

      [Tru64 UNIX]  Same as -n.

  -w width
      Sets the width of	a line to width	byte positions.	 If neither -w or -s
      are specified, the default is 72.	 If only -s is specified, the default
      is 512.  Single column output is not truncated.

      Produces the specified number of columns (the default value is 1).  The
      -e and -i	options	are assumed for	multicolumn output.  A text column
      never exceeds the	width of the page (see -l).

      Begins the display at the	specified page number (the default value is


	 When used with	arguments, the -e, -i, -n, -s, and -x options do not
	 permit	white space between the	option and its associated argument,
	 or between multiple arguments.


      The path name of a file to written.  If no file is specified, or -
      (hyphen) is specified, standard input is used.


  A heading that contains the page number, date, time, and the name of the
  file separates the output into pages.

  Unless specified, columns are	of equal width and separated by	at least one
  space.  Lines	that are too long for the page width are shortened.  If	the
  standard output is a terminal, pr does not display any error messages	until
  it has ended.	 By default, the input is separated into 66-line pages,
  including the	5-line header and 5-line footer.

  If standard output is	a terminal, diagnostic (error) messages	produced dur-
  ing the operation of pr will be deferred and printed after pr	has completed


  The following	exit values are	returned:

  0   All files	have been successfully written.

  >&gt;0  An error occurred.


   1.  To print	a file with headings and page numbers on the printer, enter:
	    pr	prog.c | lpr

       This inserts a page break in prog.c, starts each	page with a heading,
       and sends the output to the print command.  The heading consists	of
       the date	the file was last modified, the	file name, and the page

   2.  To specify a title, enter:
	    pr	-h  "MAIN  PROGRAM"  prog.c  |	lpr

       This prints prog.c with the title MAIN PROGRAM in place of the file
       name.  The modification date and	page number are	still printed.

   3.  To print	a file in multiple columns, enter:
	    pr	-3  word.lst  |	 lpr

       This prints the file word.lst in	three vertical columns.

   4.  To print	several	files side-by-side on the paper, enter:
	    pr -m -h "Members, Visitors" member.lst visitor.lst	| lpr

       This prints the files member.lst	and visitor.lst	side-by-side with the
       title Members, Visitors.

   5.  To modify a file	for later use, enter:
	    pr	-t  -e	prog.c	>&gt; prog.notab.c

       This replaces tab characters in prog.c with spaces and puts the result
       in prog.notab.c.	 Tab positions are at byte positions 9,	17, 25,	33,
       and so on.  The -e tells	pr to replace the tab characters; the -t
       suppresses the page headings.


  The following	environment variables affect the execution of pr:

      Provides a default value for the internationalization variables that
      are unset	or null. If LANG is unset or null, the corresponding value
      from the default locale is used. If any of the internationalization
      variables	contain	an invalid setting, the	utility	behaves	as if none of
      the variables had	been defined.

      If set to	a non-empty string value, overrides the	values of all the
      other internationalization variables.

      Determines the locale for	the interpretation of sequences	of bytes of
      text data	as characters (for example, single-byte	as opposed to multi-
      byte characters in arguments).

      Determines the locale for	the format and contents	of diagnostic mes-
      sages written to standard	error.

      Determines the format of the date	and time used in writing header

      Determines the location of message catalogues for	the processing of


      Your terminal, used when the -p option is	specified.
