Yes, I am copying the entire directory and its contents before running the script.
Also reference what you said:
"The other thing I noticed in your script is that every file will be over written regardless of whether any actual
changes were made or not. This is likely to give you problems when you come to verify that the changes made
where correct, or worse, make it hard to undo any mistakes as you won't know whether 1 file or every file was
changed"
How would I change it so it just writes on files I am changing??
