For Oh-My-ZSH, where do I put UNIX commands I want to executed when a new instance is started

Question

I want to have set -o vi run on every instance of my iTerm window. I know there is a file that I can add this to, but Im not sure which one.

Answer 1

set -o vi is equivilent to bindkey -v, which is the way I'd normally enable that particular option.

As with all zsh options, you can put it in the zsh startup files (ie, ~/.zshrc). The use of oh-my-zsh does not inhibit your ability to use ~/.zshrc yourself.
