Script Load Order

This markdown document will outline the order in which everything comes together.

/etc/commonprofile is sourced from /etc/profile, /etc/bash.bashrc, and /etc/zshenv.

ZSH has 3 choices when starting up. I'll denote the different "stages" by their filename. In each stage, first the /etc(/zsh)/<filename> script will be executed. After that, the $ZDOTDIR/.<filename> script will be executed.

For non-interactive sessions (i.e. executing a ZSH script), only the zshenv stage (/etc(/zsh)/zshenv followed by $ZDOTDIR/.zshenv) gets executed.

As for interactive sessions, here's a flowchart.

Interactive Session

    zshenv
    zprofile
    zshrc
    zshrclogin[zshrc]
    zlogin
    zlogout
    finished
    islogin[/"Is ZSH being launched as a login shell?"/]


    zshenv --> islogin
    islogin -->|yes| zprofile
    islogin -->|no| zshrc --> finished

    zprofile --> zshrclogin
    zshrclogin --> zlogin

    zlogin --> zlogout
    zlogout --> finished

(note: /etc/commonprofile is a symlink to common/commonprofile.sh)

(note 2: for the zlogout stage, the order of the scripts is reversed for some reason)

(note 3: Bash load order is convoluted. So I'm just gonna link to this page which already has a graph)
