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.

See the file man/man1/o__rules.so.

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 preserved. 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.
