Dash - fast but limited funcionality, great for scripts
sh - a simple link to whatever your default shell is
bash - the standard
elvish - user-friendly, but new, with a full file-browser embedded into the system.
Login
All shells launch either as login or non-login. All remote sessions without a GUI withl require authentication, and therefore will be login.
Login
These shells start by reading /etc/profile then the first of ~/.bash_profile, ~/.bash_login or ~/.profile, and load all given values.
Non-Login
Non-login shells will read /etc/bash.bashrc and then the ~/.bashrc file. You can summon the different shell perameters with the command ..
For example, so summon the file ~/.bashrc, you can perform:
. ~/.bashrc
How the logout is handled depends upon ~/.bash_logout
Defaults
The default shell config files to create for a new user are under /etc/skel.
Shellcheck
Run shellcheck script.sh on your scripts to check them for mistakes.
