crontab isn't excuting some commands

Greetings everybody,

I have an IBM P520 AIX 5.3 server machine and trying to use crontab to periodically excute a script that contains a command belongs to my software (Fast/Tools SCADA software)

I added the following line after using crontab -e

01 * * * * /mypath/myscript

I have two cases:

A) if "myscript" conatins standard SHELL commands like:

ls > /home/ls.log

In this case, it runs as excepected.

B) if "myscript" contains my application command, it doesn't run at all!
please note that this command in "myscript" file is runnig correctly if it's being typed in the KSH directly.

Am I missing somehting?

Thanks in advance

Do a search on cron or crontab in these forums. You should find the answer you are looking for.

Please read the cron FAQ section - this question has been asked/answer many times over.

Thanks a lot for replying...
It's always my habit to search before asking.. I didn't this time!

And regarding my "very common" problem, it was resolved by using the full absolute path to the commands.

Regards
