Dear Shawn,
You can use more than one file test on the same file to create a complex
logical condition.
Suppose you only want to operate on files that are both readable and writable;
you check each attribute and combine them with and:
if (-r $file and -w $file) {
...
}
Each time you perform

Thank y'all.
That's weird to read, but it makes sense easy enough.
