DESCRIPTION
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, a date and time, 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
specifed 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
double-spacing 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
character).
-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 tab).
-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 output.
-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 and argument.)
-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 carriage return).
-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
five-line 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.
-sseparator
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.
EXAMPLES
Print file1 and file2 as a double-spaced, three-column
listing headed by ``file list'':
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 -
