DESCRIPTION
The pr utility is a printing and pagination filter. If 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:
· a 5-line header that includes the page number, date, time and the
path name of the file
· a 5-line trailer consisting of blank lines
If standard output is associated with a terminal, diagnostic messages
will be deferred until the pr utility has completed processing.
When options specifying multi-column output are specified, output text
columns will be of equal width; input lines that do not fit into a text
column will be truncated. By default, text columns are separated with
at least one blank character.
OPTIONS
The following options are supported. In the following option descrip‐
tions, column, lines, offset, page, and width are positive decimal
integers; gap is a non-negative decimal integer. Some of the option-
arguments are optional, and some of the option-arguments cannot be
specified as separate arguments from the preceding option letter. In
particular, the -s option does not allow the option letter to be sepa‐
rated from its argument, and the options -e, -i, and -n require that
both arguments, if present, not be separated from the option letter.
The following options are supported for both /usr/bin/pr and
/usr/xpg4/bin/pr:
+page Begins output at page number page of the for‐
matted input.
-column Produces multi-column output that is arranged
in column columns (default is 1) and is written
down each column in the order in which the text
is received from the input file. This option
should not be used with -m. The -e and -i
options will be assumed for multiple text-col‐
umn output. Whether or not text columns are
produced with identical vertical lengths is
unspecified, but a text column will never
exceed the length of the page (see the -l
option). When used with -t, use the minimum
number of lines to write the output.
-a Modifies the effect of the -column option so
that the columns are filled across the page in
a round-robin order (for example, 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, and so forth).
-d Produces output that is double-spaced; append
an extra NEWLINE character following every NEW‐
LINE character found in the input.
-e[char][gap] Expands each input TAB character to the next
greater column position specified by the for‐
mula n *gap+1, where n is an integer >0. If gap
is 0 or is omitted, it defaults to 8. All TAB
characters in the input will be expanded into
the appropriate number of SPACE characters. If
any non-digit character, char, is specified, it
will be used as the input tab character.
-f Uses a FORMFEED character for new pages,
instead of the default behavior that uses a
sequence of NEWLINE characters. Pauses before
beginning the first page if the standard output
is associated with a terminal.
-h header Uses the string header to replace the contents
of the file operand in the page header.
-l lines Overrides 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), pr will suppress both the
header and trailer, as if the -t option were in
effect.
-m Merges files. Standard output will be formatted
so pr writes one line from each file specified
by file, side by side into text columns of
equal fixed widths, in terms of the number of
column positions. Implementations support merg‐
ing of at least nine files.
-n[char][width] Provides width-digit line numbering (default
for width is 5). The number will occupy the
first width column positions of each text col‐
umn of default output or each line of -m out‐
put. If char (any non-digit character) is
given, it will be appended to the line number
to separate it from whatever follows (default
for char is a TAB character).
-o offset Each line of output will be preceded by offset
<space>s. If the -o option is not specified,
the default offset is 0. The space taken will
be in addition to the output line width (see -w
option below).
-p Pauses before beginning each page if the stan‐
dard output is directed to a terminal (pr will
write an ALERT character to standard error and
wait for a carriage-return character to be read
on /dev/tty).
-r Writes no diagnostic reports on failure to open
files.
-s [char] Separates text columns by the single character
char instead of by the appropriate number of
SPACE characters (default for char is the TAB
character).
-t Writes neither the five-line identifying header
nor the five-line trailer usually supplied for
each page. Quits writing after the last line of
each file without spacing to the end of the
page.
-w width Sets 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 is
512.
For single column output, input lines will not
be truncated.
/usr/bin/pr
The following options are supported for /usr/bin/pr only:
-F Folds the lines of the input file. When used in
multi-column mode (with the -a or -m options),
lines will be folded to fit the current col‐
umn's width. Otherwise, they will be folded to
fit the current line width (80 columns).
-i[char][gap] In output, replaces SPACE characters with TAB
characters wherever one or more adjacent SPACE
characters reach column positions gap+1,
2*gap+1, 3*gap+1, and so forth. If gap is 0 or
is omitted, default TAB settings at every
eighth column position are assumed. If any non-
digit character, char, is specified, it will be
used as the output TAB character.
/usr/xpg4/bin/pr
The following options are supported for /usr/xpg4/bin/pr only:
-F Uses a FORMFEED character for new pages,
instead of the default behavior that uses a
sequence of NEWLINE characters.
-i[char][gap] In output, replaces multiple SPACE characters
with TAB characters wherever two or more adja‐
cent SPACE characters reach column positions
gap+1, 2*gap+1, 3*gap+1, and so forth. If gap
is 0 or is omitted, default TAB settings at
every eighth column position are assumed. If
any non-digit character, char, is specified, it
will be used as the output TAB character.
OPERANDS
The following operand is supported:
file A path name of a file to be written. If no file operands are
specified, or if a file operand is −, the standard input will
be used.
EXAMPLES
Example 1: Printing a numbered list of all files in the current direc‐
tory
example% ls -a | pr-n -h "Files in $(pwd)."
Example 2: Printing files in columns
This example prints file1 and file2 as a double-spaced, three-column
listing headed by file list:
example% pr-3d -h "file list" file1 file2
Example 3: Writing files with expanded column tabs
The following example writes file1 on file2, expanding tabs to columns
10, 19, 28, ...
example% pr-e9 -t <file1 >file2
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables
that affect the execution of pr: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES,
LC_TIME, TZ, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
