Filetest operators can be found at perlfunc:_X. Just a day or so ago swiftone showed me the "_" shortcut for performing multiple tests on one file. Yet another way to look at it.

if (-s $file && -T _) {
    # do stuff with text file > 0bytes
    }
if (-s $file && -B _) {
    # do stuff with binary file > 0bytes
    }
