in reply to Re^2: File::Find Usage with 2 subroutines
in thread File::Find Usage with 2 subroutines

One more observation meanwhile, if I change the second find call from find(\&findb, "/pqr") to find(&findb, "/pqr"), it does enter findb sub now but the file pointed by $File::Find::name is still from the /abc/xyz folder, i.e file1.

That is to be expected. It actually calls findb() before calling File::Find::find() -- that's what the syntax means. It's not a subroutine reference but a call.

Anyway, there is no problem with your code as you've posted; I'd look into other possible problem areas such as file system permissions and the logic in the rest of your script

    I found the issue, I showed wrong sequence of 'find' calls, actually the find was getting called recursively, and in that it retains the context of parent call probably. I was thinking it to be a re-entrant function, but looks like its not. This is how it looked : 

    sub finda
{
    print "In finda, $File:Find:name\n";
    find (\&findb, "/pqr");    
}

sub findb
{
    print "In findb, $File:Find:name\n";
}

find (\&finda, "/abc/xyz");

    Anyways, now I have changed the script to have the recursive nature removed, so that the two calls happens sequentially and now its working fine. Sorry for the wrong code and very thankful for your help indeed !

      It's for this reason that we *strongly* encourage posters to show the simplest example that exhibits the bad behaviour. But I'm glad you got it all sorted. :)
