Question

I want to search and replace string located in a several files via bash console.

Here is the command I use to find a string in a file:

grep "string" * -r

so the above is for searching, now I need a command to replace the string.

Is that even possible?

It’s cranky and difficult, but it’s one way to do it.

Here’s an example:

sed -i 's/ugly/beautiful/g' /home/bruno/old-friends/sue.txt

This replaces ugly with beautiful in sue.txt.
