PR(1) General Commands Manual PR(1)
NAME
pr - print file
SYNOPSIS
pr [ option ... ] [ file ... ]
DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name
of the file or a specified header, and the page number. With no file arguments, pr prints its standard input.
Options apply to all following files but may be reset between files:
-n Produce n-column output.
+n Begin printing with page n.
-b Balance columns on last page, in case of multi-column output.
-d Double space.
-en Set the tab stops for input text every n spaces.
-h Take the next argument as a page header (file by default).
-in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces.
-f Use formfeeds to separate pages.
-ln Take the length of the page to be n lines instead of the default 66.
-m Print all files simultaneously, each in one column.
-n Number the lines of each file.
-on Offset the left margin n character positions.
-sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab.
-t Do not print the 5-line header or the 5-line trailer normally supplied for each page.
-wn For multi-column output, take the width of the page to be n characters instead of the default 72.
