Hi all,
Suppose I have a folder that has a bunch of files, all named XXXX_Fred_XXX.txt
... Here, the XXX's can be anything and of variable length.

How can I change all of the files from
XXXX_Fred_XXX.txt
to
XXXX_Tony_XXX.txt

I already know how to change file extensions (ex: .txt to .sh)
but how do I change a string of text that is in the middle of a file? --- And do it for multiple files at once?
Thanks!

Without trying it, this comes to mind:
Code:
for F in *_Fred_*.txt; do
    mv -v "$F" "$(echo $F | sed 's/_Fred_/_Tony_/')"
done

Without even using sed;
Code:
for F in *_Fred_*.txt; do
  mv "$F" "${F/_Fred_/_Tony_}"
done
