pr
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. The output is separated into pages headed by a date, the name of the file or a speci-
fied header, and the page number. If there are 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.
-h Take the next argument as a page header.
-wn For purposes of multi-column output, take the width of the page to be n characters instead of the default 72.
-ln Take the length of the page to be n lines instead of the default 66.
-t Do not print the 5-line header or the 5-line trailer normally supplied for each page.
-sc Separate columns by the single character c instead of by the appropriate amount of white space. A missing c is taken to be a tab.
-m Print all files simultaneously, each in one column,
Inter-terminal messages via write(1) are forbidden during a pr.
FILES
