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.
