I am trying to find out how to tell if a given file is 30 days or older. How is that type of thing done in shell scripts.
Thanks,

As with all things *nix, there is more than one way to do the job. You might start with this idea -- or not. If you wanted to list all files in the current directory over 29 days old (you said "30 or older) this would do it:
$ find . -ctime +29 -print --OR-- those older than 29 days in your home directory $ find ~ -ctime +29 -print --OR-- to discover older rpms in the yum cache $ find /var/cache/yum -ctime +29 -print | grep .rpm
Man find is your friend. Don't be overwhelmed by its many options; start simple and build up to your goal.
