in thread How to grep for a filename for each of the keys of a hash

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)

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);

    push @array = grep (/\Q$file_name\E/i, keys %pathname_versions);

    I am getting the below error when the above piece of code is executed,what does it mean?

    Type of arg 1 to push must be array (not list assignment)

      my @array = grep (/\Q$file_name\E/i, keys %pathname_versions);

      That's the right thing.

      s/ =/,/ in that code.
