When I run echo $PATH, my output is:
/usr/bin:/bin:/usr/sbin:/sbin
But in my .zshrc, $PATH is commented out:
# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH
So, where is my PATH variable defined at? I am using oh-my-zsh, not sure if it has any difference from zsh.
There are many possibilities, but some are likelier than others. When starting Zsh, it will source the following files in this order by default:
/etc/zsh/zshenv Used for setting system-wide environment variables.
This file will always be sourced and cannot be overridden.$ZDOTDIR/.zshenv Used for setting user's environment variables.
This file will always be sourced./etc/zsh/zprofile Used for executing commands at start, will be sourced when starting as a login shell./etc/profile This file should be sourced by all Bourne-compatible shells upon login: it sets up $PATH and other environment variables and application-specific (/etc/profile.d/*.sh) settings upon login.$ZDOTDIR/.zprofile Used for executing user's commands at start, will be sourced when starting as a login shell.
$HOME/.profile is not sourced by zsh./etc/zsh/zshrc Used for setting interactive shell configuration and executing commands, will be sourced when starting as an interactive shell.$ZDOTDIR/.zshrc Used for setting user's interactive shell configuration and executing commands, will be sourced when starting as an interactive shell./etc/zsh/zlogin Used for executing commands at ending of initial progress, will be sourced when starting as a login shell.$ZDOTDIR/.zlogin Used for executing user's commands at ending of initial progress, will be sourced when starting as a login shell.
It looks as though the original value of PATH comes from /etc/paths.
