in reply to Re: A regarding glob
in thread Q regarding glob

Sorry if I didn't mention it clearly. There are many folders inside dir2. Eg: A1, B1, C1 etc: are the folder inside dir2. only A1 and B1 folders have a file names "hello.txt" Hence, I want only the names of A1 and B1. If I do glob from some other folder like glob ("../../dir1/dir2/*/hello.txt") How can I get the only folders A1 and B1. I am going through the various suggestions that you guys gave. I will try them out. Thanks

    Sorry still not clear! (And unfortunately you didn't update your posts with code-tags either).

    2 possibilities:

    • If you want the whole sub-path which fills into the wild-card, then the demonstrated code is already perfect. Try it out.

    • If you're only interested in the highest level folder do a @folders = split '/', $path for every path found by your glob and just take $folder[$index], where index is the number of folders in the "head" part.

      E.g 4 for "../../dir1/dir2/" will give you the next directory after "dir2".

    HTH! =)

      I find the solution easier with both split and

       $element =~ m!dir1/dir2/(.*)/dir3/filename!;
        It's the same solution, just less abstract and therefore more vulnerable for typos and other errors!

        Good luck! =)

      Thanks for your time.
