The first thing we’ll do is backup your existing terminal setup.
There are a lot of ways that your terminal can be set up, determined by different configuration files.
We want to remove the old ways so we can start with a clean slate.
Make back ups of the files listed below. You may get a No such file or directory
error for some of them. That’s ok.
Run these commands:
mv ~/.bashrc .bashrc.bak
mv ~/.bash_profile .bash_profile.bak
mv ~/.profile .profile.bak
mv ~/.zprofile .zprofile.bak
mv ~/.zshrc .zshrc.bak
Now, let’s move on to getting our development applications installed.
