    Is there a way to remove the entire file path from a file using regular expressions?

    I have a very long list of file names with path that I keep at cloud and it repeat every folder name for each file.
    I need to remove that to compare with other list.

    My list is like this:

    Code: Select all

              At Gabarito, see this post which explains why this simple greedy expression removes everything up to last forward slash on a line whereby it would be a bit better to use ^.*/ to explicitly start every search at beginning of a line.

                Thank you, Mofi.

                Regular Expressions is a wonderful world and I try to handle better whenever I can.
                My big problems is when it requires two passes or two ways to use parameters/variables inside the same expression, like a back reference.
                But the solutions you both are giving here was a big surprise for me. I thought that many "/" inside the path would ask for back reference feature and I became afraid just to try it.

                This forum is a nice school and I come back often to see if something new shown up here.
