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 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
       The following commands may be entered at the prompt. Commands preceeded
       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
	      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  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.
