Reading/Editing text files with bash or rc-scripts

[Lasitus]

Is there a way to edit text files with rc-scripts or would it be necessary to write in a programming language such as C?

Most people use sed, the stream editor, to do this. If you're comfortable with vi commands, you shouldn't have any problem figuring out how to use it. Quite a few ebuilds use sed for editing Makefile and configuration files, if you need some examples.
