Question

I wish to process files (.krn-files that can be read as txtfiles) and replace every occurence of { with x . Is it possible to do this on the command-line?

As I wish to do this in many files, my idea is to be able to go through all the files in a folder and process them one and one. How can this be achieved? I understand that grep may come in handy…

You can use sed:

sed -i 's/{/x/g' *
