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.

OPTIONS
       Pg accepts the following options:

       -number
              The number of lines per page. Usually, 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     pg will not pause and display (EOF) at the end of a file.

       -f     pg does 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 prompt  : , string is displayed.  If string  con-
              tains %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.

       +number
              Start at the given line.

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

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

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

       id or ^D
              Display the next halfpage. If i is given, it  is  always  inter-
              preted 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
              Behave as <newline> 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.
