I have an array "@files" which contain all the lines in a file.Some of the contents of the array ends with .plf like

//source/embark/load.c //deploy//common.c //depot/scripts/files/loading.plf

....

Now I have the below hash "Hash_filematches",I want to execute the loop for only the keys (btw,keys in this hash only contain filenames with .plf extension)*not* in the array @files.How to i write this condition? 

for my $key (keys %Hash_filematches) {
    if ($key !=~ /grep (/$key/i, @files/) {#grepping for the key value
+ and if it's not in the array then only proceed
}
}
