    Unless they run servers with something like ServerTokens Prod directive. Then the version number can be obtained via mod_perl as described in Apache2::ServerUtil documentation.

[Lady_Aleena]: tobyink, I did after I failed to get the BLOCK to work. I can't seem to get my brain around grep BLOCK, though I'm okay with grep EXPR.
[shmem]: so in the second example grep returns all true elements of the list passed
[Lady_Aleena]: Okay, so grep BLOCK is not like map BLOCK where something might need to be returned at the end.
[tobyink]: grep { $_ =~ /.*$in.*/; } @my_modules should work just fine. The problem is that you were adding on ;$_ at the end of the block. Why were you doing that?
[Lady_Aleena]: tobyink, I was thinking map.
[tobyink]: Something does need to be returned at the end not $_ though. You need to return (something that will be evaluated as) a boolean.
[Lady_Aleena]: Here is a longish map I did in the same script. my @my_modules = map { my $file = $_; $file =~ s/$module_director y(.+)\.pm/$1/; $file =~ s/\//::/g; $file; } @files;
[Lady_Aleena]: I spent half an hour trying to figure out why map was rewriting @files.
[tobyink]: If you like map you can do map { ($_ =~ /.*$in.*/) ? $_ : () } @my_modules and it will work just the same. grep is neater though.
[Lady_Aleena]: tobyink, I'll keep the grep as is. Thanks everyone!
