Introduction

crun is a light weight, easy to use, simpler cron like tool. It Executes a given program, a specified number of times, after a specified time interval. Currently in beta status.

Current Beta Version: crun-0.1.1 (beta) download (tar.gz)

How to Use

Usage: crun < No of Times > < Time Interval > < Program Namge > [Program Parameters]

crun would come handy when you need execute certain command over and over again with several time interval in between those executions. For ex. let say you wants to run netstat -na command 20 times with in time interval of 1 second. Then you can use crun with following arguments:

crun 20 1 netstat -na

crun won't return until final process is executed and returned.

Why crun? Not cron?

cron is a great tool. Even I'm using it. crun is not meant by any means to replace to cron. crun is cron like (not a daemon like cron) tool to be use for quick problems/fixes/uses. If u want to run a certain program several times you can use crun. For quick fixes/uses crun is better because,

• No need of any configurations. (You may be only use it once.)
• Gives out put to the user terminal/screen. (Where cron is a daemon)
• No restrictions. (Anybody can run crun, where cron jobs may be restricted.)
