pr(1)pr(1)Namepr - print files
Syntaxpr [ options ] [ files ]
Description
The command prints the named files on the standard output. If file is
designated by a minus sign (-), or if no files are specified the com‐
mand assumes standard input. By default, the listing is separated into
pages, each headed by the page number, a date and time, and the name of
the file.
By default, columns are of equal width, separated by at least one
space. Lines that do not fit are truncated. However, if the -s option
is used, lines are not truncated and columns are separated by the sepa‐
ration character.
If the standard output is associated with a terminal, error messages
are withheld until has finished printing.
Options
The following options can be used singly or in combination:
-a Prints multi-column output across the page.
-b Prints blank headers.
-d Double-spaces the output.
-eck Expands input tabs to character positions k+1, 2*k+1, 3*k+1,...
n*k+1. If k is 0 or is omitted, tabs are set at every eighth
position. Tab characters in the input are expanded into the
appropriate number of spaces. The default for c (any non-digit
character) is the tab character; therefore, if c is given, it
is treated as the input tab character.
-f Uses form-feed character for new pages. The default is to use
a sequence of line-feeds. The -f option causes the command to
pause before beginning the first page if the standard output is
associated with a terminal.
-h Uses the next argument as the header to be printed instead of
the file name.
-ick Replaces white space in output by inserting tabs to character
positions k+1, 2*k+1, 3*k+1,...n*k+1. If k is 0 or is omitted,
tabs are set at every eighth position. The default for c (any
non-digit character) is the tab character; therefore, if c is
given, it is treated as the input tab character.
+k Begins printing with page k (default is 1).
-k Produces k-column output (default is 1). The -e and -i options
are assumed for multi-column output.
-lk Sets the length of a page to k lines. The default is 66 lines.
-m Merges and prints all files simultaneously, one per column
(overrides the -k, and -a options).
-nck Numbers lines. The default for k is 20. The number occupies
the first k+1 character positions of each column of normal out‐
put or each line of -m output. If c, which is any non-digit
character is given, it is appended to the line number to sepa‐
rate it from whatever follows. The default for c is a tab.
-ok Offsets each line by k character positions (default is 0). The
number of character positions per line is the sum of the width
and offset.
-p Pauses before beginning each page if the output is directed to
a terminal. The command rings the bell at the terminal and
awaits a carriage return.
-r Suppresses diagnostic reports on failure to open files.
-sc Separates columns by the single character c instead of by the
appropriate number of spaces (default for c is a tab).
-t Suppresses the five-line identifying header and the five-line
trailer normally supplied for each page. The -t option causes
the command to quit printing after the last line of each file
without spacing to the end of the page.
-wk Sets the width of a line to k character positions. The default
is 72 for equal-width multi-column output; otherwise there is
no limit.
Examples
Print file1 and file2 as a double-spaced, three-column listing with the
heading: file list.
pr-3dh "file list" file1 file2
Write file1 on file2, expanding tabs to columns 10, 19, 28, 37,...:
pr-e9 -t <file1>file2
