Is there any simple way to change one line in a lot of files? I'm trying to use PHP CodeSniffer, and here's the result: ----------------------------------------------------------------- A TOTAL OF 3008 ERROR(S) AND 380 WARNING(S) WERE FOUND IN 46 FILE(S) ----------------------------------------------------------------- There a a lot of small changes on one line (for example: change `@author Olivier Pons` to `@author Olivier Pons <olivier.pons@gmail.com>`) that I'd like to do via a shell script, or even better, via a command line, and (if possible) using regular expression. Do you have any idea/suggestion/working solution for this problem? Thank you! (Note: I've already read this but it didn't help me)

I'm not sure what didn't help you in the link you provided, but `sed` seems like the right tool for this. It supports regular expression replacements, and if you pass it `-i` it will change files in-place:


$ sed -i 's/@author Olivier Pons/& /g' /path/to/your/file /path/to/another/file ...


(The `&` in the replacement is a shorthand that means "include the entire match")
