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
