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 dis-
       played. 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 stan-
       dard 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 nav-
       igation 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 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.

       +number
	      Start at the given line.

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

USAGE
       The following commands may be entered at the prompt. Commands preceded by i in this  docu-
       ment 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  rela-
       tive 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 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  rela-
	      tive 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 Expres-
	      sion 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 Expres-
	      sion 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.
