script help - removing files

Peter Gillis — Mon, 05 Aug 2002 03:32:34 GMT

I am trying to delete files older than 1 year old, every Sunday night (using cron to schedule). I have a log file being created that indicates files are being deleted - but I am also receiving a note via elm:
erase.imd2[2]: : Execute permission denied
erase.imd2[15]: : Execute permission denied
erase.imd2[2]: : Execute permission denied
erase.imd2[15]: : Execute permission denied
Why are these messages appearing?

the job erase.imd2 has perms= 777
the files to be deleted are perms=666
(should I change perm for files to be deleted to 766?)
op system=hp ux 11.00
machine d390
script file attached.
Can anyone help here...thanks
Maria.

Maria,

You need to have execute permissions on the DIRECTORIES which you "cd" to.
Hope this helps.

Deepak,
thanks for your reply....all the directories have execute permission on them.

Maria,

Does this problem occur only when you run the job thru cron? If so, it may be an environment issue or redirection issue.

Try doing a "set -x" at the top of the script to find out exactly which line of the script is cribbing.

To be more specific about Deepaks question; what user are running the cron job? And does that user have execute permission on the directory where the files are?

Another thing. Doing a 'cd' before the find&rm is generally dangerous. Should the cd fail the find will be done form the users HOME directory.

Trond

Change the find to be -print.
After the find perform an ls -l on the file and send this to the log file.
Then run an rm on this file and check the error code after the rm.
Write the error code to the log.
This way if any file fails to be removed because of permissions you can check easily.

Dear maria

Maybe i'm asking a very silly question.
Does the account used to run the script within cron have WRITE permissions on the directories ?
If not then the permission to delete files in that directory is denied. ( Thats most often what i forget to check )
