Normally, that sort of description goes with this sort of code:
If you meant something different from what that does, you need to give us a better description of what you are trying to do. (I seem to say that sort of thing a lot when responding to your posts... Have you noticed?)my @matches = grep /$filename/, keys %path_versions;
As for your usage of grep in the OP, it seems like you haven't looked at the documentation for the grep function in perl. Try this command line, and read the output that it produces.
You can do the same for any other perl function that you're unsure about. (I use this command almost every day to look things up and check out how functions are supposed to be used. When I was first learning Perl, I used it about every 20 minutes on average.)perldoc -f grep
... I want to get only the part after the last space...
The parens around the split call create an array, and the [-1] at the end takes the last element of the array.my $last_string = ( split /\s+/, $depopath )[-1];
