vii(1)			     General Commands Manual			  vii(1)

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 recent
     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  supply
     options as appropriate.
