Problem solved
Thanks to your comments above, I managed to solve the problem. I made two changes:

1. In crontab, I added an '&':
Code:
0-59/5 * * * * /usr/myFolder/start.sh &

2. I added the working directory for all files (both scripts that I execute and temporary txt files I write to). Like this:

Before:
Code:
./fileName.sh

After:
Code:
/usr/myFolder/fileName.sh

This did the trick and the start.sh file is executed every 5th minute.

I'm glad that you got it to work. With your updated scripts, what happens if you just use:
Code:
0-59/5 * * * * /usr/myFolder/start.sh

(leaving off the &)? If you're trying to avoid having cron send you mail showing output produced by your script, you can do that with redirections instead of creating extra processes:
Code:
0-59/5 * * * * /usr/myFolder/start.sh >/dev/null 2>&1

Hi Don,
Seems you have a valid point. I removed the "&" and it still works fine. Thanks.

Cheers

cron send stdout to your mailer
Did you ever check the output of your cron : by default , stdout is send to the user's mailbox.
So check :
Code:
#mailx
