As has already been mentioned, part of the problem is your quoting.
What is the value of $directories and more specifically, does it end with
a forward slash? Personally, I prefer to leave off the trailing dir
separator because IMO it makes it more clear later when the $filename is
added.
Why are you using a system call instead of the more portable move() of
mv() function from File::Copy, which is a core module?
use File::Copy qw(cp mv);
...
...
mv("$directories/$filename", "$directories/deleted_keys")
or warn qq(Failed to move "$directories/$filename" to
"$directories/deleted_keys" <$!>);
