PG(1)                             User Commands                            PG(1)



NAME
       pg - browse pagewise through text files

SYNOPSIS
       pg [-amount] [-p prompt] [-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 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.

OPTIONS
       pg accepts the following options:

       +number
              Start at the given line number.

       +/pattern/
              Start at the line containing the Basic Regular Expression pattern
              given.

       -number
              The number of lines per page.  By default, this is the number of
              CRT lines minus one.

       -c     Clear the screen before a page is displayed, if the terminfo entry
              for the terminal provides this capability.

       -e     Do not pause and display (EOF) at the end of a file.

       -f     Do not split long lines.

       -n     Without this option, commands must be terminated by a newline
              character.  With this option, pg advances once a command letter is
              entered.

       -p string
              Instead of the normal prompt :, string is displayed.  If string
              contains %d, its first occurrence is replaced by the number of the
              current page.

       -r     Disallow the shell escape.

       -s     Print messages in standout mode, if the terminfo entry for the
              terminal provides this capability.

       -V, --version
              Disaplay version information and exit.

       -h, --help
              Display help text and exit.

COMMANDS
       The following commands may be entered at the prompt.  Commands preceded
       by i in this document accept a number as argument, positive or negative.
       If this argument starts with + or -, it is interpreted relative to the
       current position in the input file, otherwise relative to the beginning.

       i<Enter>
              Display the next or the indicated page.

       id or ^D
              Display the next halfpage.  If i is given, it is always
              interpreted relative to the current position.

       il     Display the next or the indicated line.

       if     Skip a page forward.  i must be a positive number and is always
              interpreted relative to the current position.

       iw or iz
              As <Enter> except that i becomes the new page size.

       . or ^L
              Redraw the screen.

       $      Advance to the last line of the input file.

       i/pattern/
              Search forward until the first or the i-th occurrence of the Basic
              Regular Expression pattern is found.  The search starts after the
              current page and stops at the end of the file.  No wrap-around is
              performed.  i must be a positive number.

       i?pattern? or i^pattern^
              Search backward until the first or the i-th occurrence of the
              Basic Regular Expression pattern is found.  The search starts
              before the current page and stops at the beginning of the file.
              No wrap-around is performed.  i must be a positive number.

       The search commands accept an added letter.  If t is given, the line
       containing the pattern is displayed at the top of the screen, which is
       the default.  m selects the middle and b the bottom of the screen.  The
       selected position is used in following searches, too.

       in     Advance to the next file or i files forward.

       ip     Reread the previous file or i files backward.

       s filename
              Save the current file to the given filename.

       h      Display a command summary.

       !command
              Execute command using the shell.

       q or Q Quit.

       If the user presses the interrupt or quit key while pg reads from the
       input file or writes on the terminal, pg will immediately display the
       prompt.  In all other situations these keys will terminate pg.
