What Others Think

Interesting. I'll probaby use sed -i because that's what I've remembered for years. Also just a warning to people running this command who might not have a full grasp of it. It is a recursive command that does a global find and replace on all files using the regex pattern you specify or just and without asking for conformation. You may replace something unintentionally. When running find exec/replace or piping to xargs I will always run the find command just to see what it is going to match. You can't do that with this command. In that case I'd make a backup of everything with cp -a if at all possible. Then after running the command above, run ls -ltR *, and it will show you which files were modified at the top of each directory listing. You might know of files you weren't expecting the command to touch, or if you don't, you can just compare the changes with your backup and the diff command making sure that nothing unexpected happened. I'm just overly cautious. If you're not putting in regex and just using a simple strings as the command example shows, you'll be fine.
