I'm trying to add a line of code
source /home/...
to the end of a file. I think I need to open this file in an editor (using Atom), edit the file, save the file, and then I'll re-run the command that told me to do all of this. So how do I open a file (.bashrc, if it matters) with atom and then how do I save it so I overwrite the old file? Thanks a bunch!!
