It’s hard to say what’s going wrong when you don’t show either the loop code or the contents of $fil_nm.

However, it’s not necessary to use system — the core module File::Copy has a move function. Here’s a guess at what you’re trying to do:

use File::Copy;
my @files_to_move = split(/\s+/, $fil_nm);  # assuming $fil_nm contain
+s a space-separated list of files to move
move($_, './reports') for @files_to_move;
