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

       /dev/tty?  to suspend messages.

DIAGNOSTICS
