pr - print file
pr [ option ... ] [ file ... ]
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name
of the file or a specified header, and the page number. With no file arguments, pr prints its standard input.
Options apply to all following files but may be reset between files:
-n Produce n-column output.
+n Begin printing with page n.
-b Balance columns on last page, in case of multi-column output.
-d Double space.
-en Set the tab stops for input text every n spaces.
-h Take the next argument as a page header (file by default).
-in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces.
-f Use formfeeds to separate pages.
-ln Take the length of the page to be n lines instead of the default 66.
-m Print all files simultaneously, each in one column.
-n Number the lines of each file.
-on Offset the left margin n character positions.
-sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab.
-t Do not print the 5-line header or the 5-line trailer normally supplied for each page.
-wn For multi-column output, take the width of the page to be n characters instead of the default 72.

pr -- print files
pr [+page] [-column] [-adFfmprt] [[-e] [char] [gap]] [-L locale] [-h header] [[-i] [char] [gap]] [-l lines] [-o offset] [[-s] [char]] [[-n]
[char] [width]] [-w width] [-] [file ...]
The pr utility is a printing and pagination filter for text files. When multiple input files are specified, each is read, formatted, and
written to standard output. By default, the input is separated into 66-line pages, each with
o A 5-line header with the page number, date, time, and the pathname of the file.
o A 5-line trailer consisting of blank lines.
If standard output is associated with a terminal, diagnostic messages are suppressed until the pr utility has completed processing.
When multiple column output is specified, text columns are of equal width. By default text columns are separated by at least one <blank>.
Input lines that do not fit into a text column are truncated. Lines are not truncated under single column output.
In the following option descriptions, column, lines, offset, page, and width are positive decimal integers and gap is a nonnegative decimal
Begin output at page number page of the formatted input.
Produce output that is columns wide (default is 1) that is written vertically down each column in the order in which the text is
received from the input file. The options -e and -i are assumed. This option should not be used with -m. When used with -t, the min-
imum number of lines is used to display the output. (To columnify and reshape text files more generally and without additional format-
ting, see the rs(1) utility.)
-a Modify the effect of the -column option so that the columns are filled across the page in a round-robin order (e.g., when column is 2,
the first input line heads column 1, the second heads column 2, the third is the second line in column 1, etc.). This option requires
the use of the -column option.
-d Produce output that is double spaced. An extra <newline> character is output following every <newline> found in the input.
Expand each input <tab> to the next greater column position specified by the formula n*gap+1, where n is an integer > 0. If gap is
zero or is omitted the default is 8. All <tab> characters in the input are expanded into the appropriate number of <space>s. If any
nondigit character, char, is specified, it is used as the input tab character.
-F Use a <form-feed> character for new pages, instead of the default behavior that uses a sequence of <newline> characters.
-f Same as -F but pause before beginning the first page if standard output is a terminal.
Use the string header to replace the file name in the header line.
In output, replace multiple <space>s with <tab>s whenever two or more adjacent <space>s reach column positions gap+1, 2*gap+1, etc. If
gap is zero or omitted, default <tab> settings at every eighth column position is used. If any nondigit character, char, is specified,
it is used as the output <tab> character.
Use locale specified as argument instead of one found in environment. Use "C" to reset locale to default.
Override the 66 line default and reset the page length to lines. If lines is not greater than the sum of both the header and trailer
depths (in lines), the pr utility suppresses output of both the header and trailer, as if the -t option were in effect.
-m Merge the contents of multiple files. One line from each file specified by a file operand is written side by side into text columns of
equal fixed widths, in terms of the number of column positions. The number of text columns depends on the number of file operands suc-
cessfully opened. The maximum number of files merged depends on page width and the per process open file limit. The options -e and -i
Provide width digit line numbering. The default for width, if not specified, is 5. The number occupies the first width column posi-
tions of each text column or each line of -m output. If char (any nondigit character) is given, it is appended to the line number to
separate it from whatever follows. The default for char is a <tab>. Line numbers longer than width columns are truncated.
Each line of output is preceded by offset <spaces>s. If the -o option is not specified, the default is zero. The space taken is in
addition to the output line width.
-p Pause before each page if the standard output is a terminal. pr will write an alert character to standard error and wait for a car-
riage return to be read on the terminal.
-r Write no diagnostic reports on failure to open a file.
Separate text columns by the single character char instead of by the appropriate number of <space>s (default for char is the <tab>
-t Print neither the five-line identifying header nor the five-line trailer usually supplied for each page. Quit printing after the last
line of each file without spacing to the end of the page.
Set the width of the line to width column positions for multiple text-column output only. If the -w option is not specified and the -s
option is not specified, the default width is 72. If the -w option is not specified and the -s option is specified, the default width
file A pathname of a file to be printed. If no file operands are specified, or if a file operand is '-', the standard input is used. The
standard input is used only if no file operands are specified, or if a file operand is '-'.
The -s option does not allow the option letter to be separated from its argument, and the options -e, -i, and -n require that both arguments,
if present, not be separated from the option letter.
If pr receives an interrupt while printing to a terminal, it flushes all accumulated error messages to the screen before terminating.
The pr utility exits 0 on success, and 1 if an error occurs.
Error messages are written to standard error during the printing process (if output is redirected) or after all successful file printing is
complete (when printing to a terminal).
