Shell Programming and Scripting

Hi all,

I'm trying to work on a script to delete files older then 31 day's in certain directories. Now, that works, but in one directory there are 3 other maps which contains files that can be deleted but one map which contains files that can't be deleted.

My current command is: find /ontw/log -type f -mtime +31 -exec rm {} \;
The directory that should be excluded during deletion is: /ontw/log/lost+found

Thank you for your time!

Code:

 find /ontw/log -type f -mtime +31 |grep -v  /ontw/log/lost+found | xargs rm

Thanks, that worked perfect

After trying it again I received this error:
user@/ontw/bin/delete$ find /ontw/log -type f -mtime +31 |grep -v /ontw/log/lost+found | xargs rm
find: cannot read dir /ontw/log/lost+found: Permission denied
usage: rm [-fiRr] file ...

Does anyone know what the problem can be?

it is throwing this error message as you don't have access to read /ontw/log/lost+found directory

Well thank you but is it possible to exclude it then during the find command? In other words, is it possible to exclude a folder that you can't read before you try to delete the files in this folder?

Code:

find /ontw/log -type d ! -name "/ontw/log/lost+found"   -mtime +31  | xargs rm

The same problem. We should have a command that excludes the directory before reading the other directories in /ontw/log and this doesn't happen here.
First he's going to read all the directories in /ontw/log and that's why I get the error.
