Question

Hello I have a colleague of mine who is a procedural code developer and has same smtp server name sitting in 120 different files, now I have to change them to something else. But doing that one by one would be impossible. I am using “grep” to recursively search for a string in all the files sitting in that directory. But I am not sure if grep can edit the file and replace it with the new string.

Thanks

Shouldn’t this be on serverfault?

Anyway, you should be looking at a combination of find and sed.

Possibly something like:

find . -iname "<filepattern>" -exec sed -e "s/<regex to look for>/<replacement>/g" -i {} \;
