Use 'perldoc -f -x' to get to the manual page of the filetest operators. To check if for example a file is executable, you would use if (-x $file) { ... }

To check if a file is corrupted there is no easy or generally usable way. If the file is a perl script you could try to check it with 'perl -c'
