Faster than Crontab

majorlinux · #1 27th March 2009, 12:41 AM

Is there anything faster than crontab? I am working on a project and need crontab to run faster than it currently does. Is that possible or is there software I can install to get it to do that?

Do you mean sub minute resolution? Crontab, anacron and 'at' all can only be set to do things at a time specified to the minute.

Yeah. That's what I want. I don't want to have to wait a minute to process the information. Its holding up the website's functionality seeing as the information doesn't quite take a minute to process.

Set the run interval in your script.

How would you do something like that? I have the crontab running a script.

Or write your own application that would receive a signal or a communication via socket from the other software. That would tell it to start right now and handle that processing as needed.

Sounds like you didn't write it.

In that case, use marko's suggestion or just a simple script calling it on set intervals.

use the "watch" command

watch -n<time_to_loop> <script_to_run>

where time_to_loop is in seconds

Example:

Lets say you have a script called monitor.sh. You can run it every second by doing

Code:

watch -n1 ./monitor.sh

or every 3 minutes by doing

Code:

watch -n180 ./monitor.sh

Good luck!
