NAME
       vii - buffer and	display	output

SYNOPSIS
       vii [ option...	]
       vii -Help
       vii -VERSion

DESCRIPTION
       The  vii	 command  accepts  input  from the standard input and displays
       pages of	the input on the crt.  These pages are delimited by form-feeds
       (or EOF)	and only as much as will fit on	the screen will	be displayed.

       The vii command can also	repeatedly execute a command, and the most re-
       cent output is displayed.

OPTIONS
       The following options are understood:

       -Execute	string
	       The given string	is executed.  The command should be in quotes.

       -Interval number
	       Commands	executed with the -Execute option will	be  reexecuted
	       after the given interval	in seconds.

       -Terminal string
	       Use  the	terminal type given, rather than the type given	in the
	       TERM environment	variable.

       -Help   Display some help on how	to used	the vii(1) command.

       -VERSion
	       Display the versin of the vii(1)	command.

COMMANDS
       The following commands may be used to navigate the displayed text

       q Q     Quit out	of vii(1).  As much of possible	of the display is pre-
	       served.	The interrupt key (usually ^C) will also cause	vii(1)
	       to quit.

       ^L ^R   Redraw  the screen.  This can be	useful if a background process
	       has overwritten the display.

       j ^E CR Scroll down one line.

       k ^Y    Scroll up one line.

       J ^F SP Scroll down one screen of text.

       K ^B    Scroll up one screen of text.

       c C ^C  Show the	date and time in the top right corner of the screen.

       t T ^T  Show the	time in	the top	right corner of	the screen.

       d D ^D  Show the	date in	the top	right corner of	the screen.

       p P ^P  Show the	line position in the top right corner of the screen.

EXAMPLES
       To display the process state every 15 seconds,
	use the	following command:
	      vii -e "ps axu" -i 15
       If your shell does not have aliases, this shell script will do much the
       same thing:
	      #!/bin/sh
	      while :
	      do
		      ps axu
		      echo | tr	'\12' '\14'
		      sleep 15
	      done | vii
       If you don't have a Berkeley style ps(1)	command, you will need to sup-
       ply options as appropriate.
