Need Help??

As per above comments you use the quotemeta function.
And
Insist of the below code

grep (/$filename/i, $key) foreach my $key (keys %path_versions)
[download]

You will try the below code. Here, you no need to use the foreach loop. You directly pass 'hash keys'.

@array = grep (/$filename/, keys %path_versions);
