       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	 stan‐
       dards as follows:

       pr:  XCU5.0

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

       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.)
       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.
       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.	 Uses a formfeed char‐
       acter to advance to a new page. (Otherwise, pr  issues  a  sequence  of
       newline characters.)  Does not pause before beginning the first page if
       the standard output is a terminal.  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 character.)  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.  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.)  Indents	each  line  of
       output  by  offset byte positions (the default is 0).  This is in addi‐
       tion to output width (see -w).  Pauses before beginning	each  page  if
       the  output is directed to a terminal.  (pr sounds the bell at the ter‐
       minal and waits for you to press <Return>.)  Does not display  diagnos‐
       tic 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).  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.  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 1).


	      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
       during  the  operation  of pr will be deferred and printed after pr has
       completed processing.

       The following exit values are returned: All files  have	been  success‐
       fully written.  An error occurred.

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

	      This  prints  the	 file  word.lst in three vertical columns.  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.	 To modify a  file  for	 later
	      use, enter: pr  -t  -e  prog.c  > 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 char‐
	      acters; the -t suppresses the page headings.

       The following environment variables affect the execution	 of  pr:  Pro‐
       vides  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 vari‐
       ables contain an invalid setting, the utility behaves as if none of the
       variables  had been defined.  If set to a non-empty string value, over‐
       rides 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 messages written to standard error.	Deter‐
       mines  the  format  of  the date and time used in writing header lines.
       Determines the location of message catalogues  for  the	processing  of

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

       Commands:  cat(1), expand(1), mesg(1)
