    1. login shell: A login shell logs you into the system as a specific user, necessary for this is a username and password. When you hit ctrl+alt+F1 to login into a virtual terminal you get after successful login: a login shell (that is interactive). Sourced files: /etc/profile and ~/.profile for Bourne compatible shells (and /etc/profile.d/*) ~/.bash_profile for bash /etc/zprofile and ~/.zprofile for zsh /etc/csh.login and ~/.login for csh non-login shell: A shell that is executed without logging in, necessary for this is a current logged in user. When you open a graphic terminal in gnome it is a non-login (interactive) shell. Sourced files: /etc/bashrc and ~/.bashrc for bash interactive shell: A shell (login or non-login) where you can interactively type or interrupt commands. For example a gnome terminal (non-login) or a virtual terminal (login). In an interactive shell the prompt variable must be set ($PS1). Sourced files: /etc/profile and ~/.profile /etc/bashrc or /etc/bash.bashrc for bash non-interactive shell: A (sub)shell that is probably run from an automated process you will see neither input nor output when the calling process don't handle it. That shell is normally a non-login shell, because the calling user has logged in already. A shell running a script is always a non-interactive shell, but the script can emulate an interactive shell by prompting the user to input values. Sourced files: /etc/bashrc or /etc/bash.bashrc for bash (but, mostly you see this at the beginning of the script: [ -z "$PS1" ] && return. That means don't do anything if it's a non-interactive shell). depending on shell; some of them read the file in the $ENV variable.
    1. then if your system does not source ~/.bashrc by default via /etc/profile you should source it in ~/.bash_profile file so any login shell will have access also to the same environment like non login sessions.
    2. When you execute commands in non login shell like ssh server command or scp file server:~ or sudo(without -i) or su (without -l) it will execute ~/.bashrc
