pr(1) General Commands Manual pr(1)
pr - print files
The command prints the named files on the standard output. If file is or if no files are specified, the standard input is assumed. 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. If the option is used, lines
are not truncated and columns are separated by the separation character.
If the standard output is associated with a terminal, error messages are withheld until has completed printing.
The following options can be used singly or combined in any order:
Begin printing with page
k (default is 1).
Produce k-column output (default is 1). This option should not be used with The options and are assumed for multi-column output.
Produce k-column output, same as
Print multi-column output across the page.
This option is appropriate only with the option.
Merge and print all files simultaneously,
one per column (overrides the and options).
Double space the output.
Expand input tabs to character positions k+1, 2xk+1, 3xk+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 nondigit
character) is given, it is treated as the input tab character (default for c is the tab character).
In output, replace white space wherever possible by inserting tabs to character positions k+1, 2xk+1, 3xk+1, etc. If k is 0
or is omitted, default tab settings at every eighth position are assumed. If c (any nondigit character) is given, it is
treated as the output tab character (default for c is the tab character).
Provide k-digit line numbering (default for k is 5). The number occupies the first k+1 character positions of each column of nor-
mal output or each line of output. If c (any nondigit character) is given, it is appended to the line number to separate
it from whatever follows (default for c is a tab).
Set the width of a line to
k character positions (default is 72 for equal-width, multi-column output; no limit otherwise). Width specifications are
only effective for multi-columnar output.
Offset each line by
k character positions (default is 0). The number of character positions per line is the sum of the width and offset.
Set the length of a page to
k lines (default is 66). If k is less than what is needed for the page header and trailer, the option is in effect; that
is, header and trailer lines are suppressed in order to make room for text.
Use the next argument as the header to be printed
instead of the file name.
Pause before beginning each page
if the output is directed to a terminal rings the bell at the terminal and waits for a Return).
Use 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.
Same as Provided for backwards compatibility.
Print no diagnostic reports on failure to open files.
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.
Separate columns by the single character
c instead of by the appropriate number of spaces (default for c is a tab).
determines the interpretation of text and the arguments associated with the and options as single-byte and/or multi-byte characters.
determines the format and contents of date and time strings.
determines the language in which messages are displayed.
If or is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty
variable. If is not specified or is set to the empty string, a default of (see lang(5)) is used instead of
If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to See envi-
International Code Set Support
Single-byte and multi-byte character code sets are supported.
The returns the following values upon completion:
One or more of the input
files do not exist or cannot be opened.
Print and as a double spaced, three column listing headed by ``file list'':
