find syntax, exclude certain extensions and filter by age

[supergper]

I'm trying to find all the files in a specified directory that do NOT end in .archived or .error and are older than 30 mins. Currently I have:

find /opt/edi/incoming -type f \! \( -name "*.archived" -name "*.error" \) -cmin 30

But I keep returning files that end in those extensions and I'm not sure if I'm using -cmin correctly??? Any help?

If there is a better way to do this (perl, etc) I'm open to options, this is for a nagios check.

Try this:

find /opt/edi/incoming -type f \( ! -name "*.archived" -a ! -name "*.error" \) -cmin +30

That works perfect, thanks!
