There is a standard solution to this: use the "root" user to access every file, regardless of who owns it.
The other possibility would be to put your cron job into the crontab of the UID which owns the files. Every user has a separate crontab, which is a readable ASCII file. The location depends on the UNIX you are using, for instance in IBMs AIX the crontabs are located in "/var/spool/cron/crontabs/<user>" where "<user>" is the user accounts name.
Your "find" command seems to be correct save for a missing starting directory:
find <some_start_dir> –name “*.html” –mtime +30 –exec rm –f {} \;
but keep in mind that a process started from cron does not inherit the environment like a process started from an interactive shell does. if you write "find" instead of "/usr/bin/find" chances are you get a "command not found" error, because the PATH variable, which you have probably set in your login shell is not set for cron jobs. (This is, btw., the absolute number-1-error in this and the Shell-Programming-and-Scripting forum.)
I hope this helps.
