PG(1)                            User Commands                           PG(1)

NAME
       pg - browse pagewise through text files

SYNOPSIS
       pg  [  -number  ]  [ -p string ] [ -cefnrs ] [ +line ] [ +/pattern/ ] [
       file . . . ]

DESCRIPTION
       Pg displays a text file on a CRT one screenful  at  once.   After  each
       page, a prompt is displayed. The user may then either press the newline
       key to view the next page or one of the keys described below.

       If no filename is given on the command line,  pg  reads  from  standard
       input.   If  the standard output is not a terminal, pg acts like cat(1)
       but precedes each file with its name if there is more than one.

       If input comes from a pipe, pg stores the data in a buffer  file  while
       reading to make navigation possible.
