TSR's in linux
 

Hi, this is swanand shende
We are doing a project in which we want to shedule a particular event every 30 minutes or so. In dos, we used to write a tsr.
Is there anything like tsr's in linux? If so anything equivalent ? How to do it?

Use cron - it's a task scheduler. I don't know how to use it, but have a look at the man page or google for it. It allows tasks to be run at any sort of interval. Perhaps you could write a script and have it executed every half hour.

tsr is something to give an appearance of multitasking on systems that can't actually multitask. this is not necessary in linux since it is a true multitasking system as the above poster said all you need to do is set up a cron job and your script / program will run as often as you like.
