Hello Monks,
I'd like to provide users with meaningful error messages, still, plainly giving out the value of $! might pose a security problem. 
  # something happened
  print "Sorry guys: an error occured: ".$!

It's okay to do so if $! = "Permission denied". But what if there's a path in it?, like $! = "/var/www/site/dir/that/you/should/not/know/file.ext, file not found."

Any hints on what I should tink of when implementing a filter($!)? Or is there a module I don't know?

In reply to Filtering error string $!, for example remove paths by isync
