How to set environment variables in bash and zsh
The operation is the same on both Bash and zsh, with the caveat that to persist them you need to use .bashrc and .zshrc, respectively.
Setting them in the shell is the same:
$ export VARIABLE=somethingTo make sure it was set, type
$ $VARIABLEIf you edit a dot file, to apply the changes to the current shell use source .dotfile.
This works for Bash and Zsh.
With Fish you prepend env:
