pr is used to format and print the contents of a file. If file is -, or
if no files are specified, pr assumes standard input. pr prints the
named files on standard output.
By default, the listing is separated into pages, each headed by the page
number, the date and time that the file was last modified, and the name
of the file. Page length is 66 lines which includes 10 lines of header
and trailer output. The header is composed of 2 blank lines, 1 line of
text ( can be altered with -h), and 2 blank lines; the trailer is 5
blank lines. For single column output, line width may not be set and is
unlimited. For multicolumn output, line width may be set and the default
is 72 columns. Diagnostic reports (failed options) are reported at the
end of standard output associated with a terminal, rather than
interspersed in the output. Pages are separated by series of line feeds
rather than form feed characters.
By default, columns are of equal width, separated by at least one space;
lines which do not fit are truncated. If the -s option is used, lines are
not truncated and columns are separated by the separator character.
Either -column or -m should be used to produce multi-column output. -a
should only be used with -column and not -m.
Command line options are
+page Begin printing with page numbered page (default is 1).
-column Print column columns of output (default is 1). Output appears
as if -e and -i are turned on for multi-column output. May not
use with -m.
-a Print multi-column output across the page one line per column.
columns must be greater than one. If a line is too long to fit
in a column, it is truncated.
-m Merge and print all files simultaneously, one per column. The
maximum number of files that may be specified is eight. If a
line is too long to fit in a column, it is truncated. May not
use with -column.
-d Double-space the output. Blank lines that result from doublespacing
are dropped when they occur at the top of a page.
-eck Expand input tabs to character positions k+1, 2*k+1, 3*k+1,
etc. If k is 0 or is omitted, default tab settings at every
eighth position are assumed. Tab characters in the input are
expanded into the appropriate number of spaces. If c (any
non-digit character) is given, it is treated as the input tab
character (default for c is the tab character).
-ick In output, replace white space wherever possible by inserting
tabs to character positions k+1, 2*k+1, 3*k+1, etc. If k is 0
or is omitted, default tab settings at every eighth position
are assumed. If c (any non-digit character) is given, it is
treated as the output tab character (default for c is the tab
-nck Provide k-digit line numbering (default for k is 5). The
number occupies the first k+1 character positions of each
column of single column output or each line of -m output. If c
(any non-digit character) is given, it is appended to the line
number to separate it from whatever follows (default for c is a
-wwidth Set the width of a line to width character positions (default
is 72). This is effective only for multi-column output (-
column and -m). There is no line limit for single column
-ooffset Offset each line by offset character positions (default is 0).
The number of character positions per line is the sum of the
width and offset.
-llength Set the length of a page to length lines (default is 66). -l0
is reset to -l66. When the value of length is 10 or less, -t
appears to be in effect since headers and trailers are
suppressed. By default, output contains 5 lines of header and
5 lines of trailer leaving 56 lines for user-supplied text.
When -llength is used and length exceeds 10, then length-10
lines are left per page for user supplied text. When length is
10 or less, header and trailer output is omitted to make room
for user supplied text.
-h header Use header as the text line of the header to be printed instead
of the file name. -h is ignored when -t is specified or
-llength is specified and the value of length is 10 or less.
(-h is the only pr option requiring space between the option
-p Pause before beginning each page if the output is directed to a
terminal (pr will ring the bell at the terminal and wait for a
-f Use single form-feed character for new pages (default is to use
a sequence of line-feeds). Pause before beginning the first
page if the standard output is associated with a terminal.
-r Print no diagnostic reports on files that will not open.
-t Print neither the five-line identifying header nor the fiveline
trailer normally supplied for each page. Quit printing
after the last line of each file without spacing to the end of
the page. Use of -t overrides the -h option.
Separate columns by the single character separator instead of
by the appropriate number of spaces (default for separator is a
tab). Prevents truncation of lines on multicolumn output
unless -w is specified.
Print file1 and file2 as a double-spaced, three-column listing headed by
pr -3dh "file list" file1 file2
Copy file1 to file2, expanding tabs to columns 10, 19, 28, 37, ... :
pr -e9 -t <file1 >file2
Print file1 and file2 simultaneously in a two-column listing with no
header or trailer where both columns have line numbers:
pr -t -n file1 | pr -t -m -n file2 -
/dev/tty* If standard output is directed to one of the special files
/dev/tty*, then other output directed to this terminal is
delayed until standard output is completed. This prevents
error messages from being interspersed throughout the
cat(1), fold(1), pg(1).
