Question

What is the most correct regular expression (regex) for a UNIX file path?

For example, to detect something like this:

/usr/lib/libgccpp.so.1.0.2
         


        

Answer 1

The proper regular expression to match all UNIX paths is: [^\0]+

That is, one or more characters that are not a NUL.
