Vrun

[Karl Meiser]

This is a simple program I wrote to mimick a program named 'display'
for xenix on a '386.  Its not quite as fancy,   but its public domain
and it does its job.

"vrun.c" follows:

#include <stdio.h>
#include <curses.h>
#include <signal.h>

/*
 *
 *  Visual Run V1.0	(C)  Karl Meiser
 *
 *	This is a simple little program that I wrote up to be helpfull
 *	for monitoring various things.  Its fairly simple to use,
 *	simply define your $TERM and run.
 *
 *		Usage: vrun command [args]
 *
 *	Because of the way its set up,  it can even be used with
 *	shell scipts through the notation 'vrun [kc]sh script'.
 *
 *	The screen is limited to 24 lines.
 *
 *	To compile:
 *
 *		cc vrun.c -lcurses -ltermcap -o vrun
 *

 *	This software is free and I place no restrictions on usage,
 *	copying, or modification as long as my name remains on it as
 *	well as this message.
 *
 *	I am in no way liable for this software,  or its results.
