[linux] Cronjobs ?

[Snell]

I made a cron job to execute a script every minute.

* * * * * "/home/user/crontest.sh"

The script:

date >> "/home/user/test.txt"
sleep 10m

As you can see, the script output the date and time to the text file "test.txt" and wait for 10 Minutes.

Here is the output:

Thu Sep 16 19:06:01  2010
Thu Sep 16 19:07:01  2010
Thu Sep 16 19:08:01  2010
Thu Sep 16 19:09:01  2010

However, I want the execution in the script to be complete before re-executing the script again.

that's is the output should be like this:

Thu Sep 16 19:06:01 2010
Thu Sep 16 19:00:01 2010
Thu Sep 16 19:10:01 2010
Thu Sep 16 19:20:01 2010

Any one knows how this can be done ??


(I've made this just as example but I'll use the script for some other purposes)

:\ lol run it after every ten minutes rather than every minute

The sleep 10m really does nothing as you are not looping that script.

So if what you are trying to do is make sure 10 minutes is passed than run it every 10 minutes as gunda said.

If want the 10 minute loop for something else your only other choice would be create a file with last run date in it or use the creation date to check if it has been 10 minutes and then create a new file and run your code.
