Hi Mr Dynaweb (as it looks like you who always replies to these things, but hello to anyone else who wants to help too:)
I want to add a cron job to run every day, which deletes all files in a certain directory that are more than 3 days old.
I have gone to the Cpanel, and adding a job looks fairly straightforward, but before entering commands I want to make sure I know what I'm doing.
I have very little unix experience (only that which I have gained form running hosted websites for a few years), and want to make sure I know the commands that will filter the set of files being deleted to ONLY those older that 3 days.
As a side issue, these files are created by a php script running on the site, so I wonder about the permissions, and I wonder if there is a heirarchy to how permissions are structured. (for example is there a user 'apache, or php who may be the owner of the files?)
