UNIX for Dummies Questions & Answers

Our site has a page that creates a jpeg graph everytime you load it. I have written a very simple cron job (rm *.jpeg) to delete the graphs once a day. This doesn't happen because the jpegs are owned by nobody:nobody and are write protected.

When I do the job manually I am always asked 'are you sure you want to delete....' which obviously cron doesn't like. If I put a jpeg in the folder that is owned by a standard owner it gets deleted so I know the syntax is correct.

My question is this: Is it easier to change the ownership of jpegs so that they are created with the standard owner or is it easier to make my cron job delete the jpegs even though they are protected?

And how do I go about implementing which ever is easier?

Try:

Code:

$ rm -f jpegfile.jpg

In your cronjob.

I am puzzled as to why the jpeg file ends up being owned by nobody:nobody but anyway the above may be the simplest solution.

from the man pages:

Code:

       -f, --force
              ignore nonexistent files, never prompt

Thanks for that.
