Search and replace utility
Hi everybody.

Does anyone use a command line search and replace tool?

For example, say I want to go through every text file in a directory and replace "devshed" with "devshedforums"

I found one at one time but by accident. Now I can't find it and have been searching forever to find something!

This would save me ALOT of time...

i use sed and the bash for this task:
Code:
for i in *; do
  cat "$i" | sed -e "s/devshed/devshedforums/" >/tmp/tmpfile
  cat /tmp/tmpfile > "$i"
done

I use perl - here's the command



perl -p -i.bak -e 's#old_string#new_string#g' /path/files

-p means loop
-i.bak will copy originals to .bak, use just -i for no backup if you are sure
-e designates expression.

awk or sed would do the trick as well.
