in reply to Array Element Substitution

The way I see it, you have a certain orig_name=>new_name mapping (a hash) where $hash{$orig_name}=$new_name. And you wish to replace all orig_name in your log_file with new_name.

#Open the file and slurp it into an array @lines #Search orig_name in line and replace it with new_name map{s/$orig_name/$new_name/g} @lines; #Write the transformed array into file again
