I always use an if contruct, although I guess it's technically still test:

if [ -f *.log ]; then
        echo "File exists"
fi

This tests if the file exists and is a regular file, you can use -d to
test for a directory, etc...

For a quicker reply, I'll let someone else answer the other question,
since my perl is rusty at the moment.
