NAME         top

       pg - browse pagewise through text files

SYNOPSIS         top

       pg [-amount] [-p prompt] [-cefnrs] [+line] [+/pattern/] [file...]

DESCRIPTION         top

       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         top

       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
              Display version information and exit.

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

COMMANDS         top

       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.
