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 occurence 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

       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 occurence 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  occurence  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.

ENVIRONMENT VARIABLES

       The following environment variables affect the behaviour of pg:

       COLUMNS
              Overrides the system-supplied number of columns if set.

       pg expects the terminal tabulators to set on eight positions.

       Files that include NUL characters cannot be displayed by pg.
