More, from an old StackExchange thread:

"A shell is the generic name for any program that gives you a text-interface
to interact with the computer. You type a command and the output is shown on
screen.

"Many shells have scripting abilities: Put multiple commands in a script and
the shell executes them as if they were typed from the keyboard. Most shells
offer additional programming constructs that extend the scripting feature
into a programming language.

"On most Unix/Linux systems multiple shells are available: bash, csh, ksh,
sh, tcsh, zsh just to name a few. They differ in the various options they
give the user to manipulate the commands and in the complexity and
capabilities of the scripting language.

"Interactive: As the term implies: Interactive means that the commands are
run with user-interaction from keyboard. E.g. the shell can prompt the user
to enter input.

"Non-interactive: the shell is probably run from an automated process so it
can't assume it can request input or that someone will see the output. E.g.,
maybe it is best to write output to a log file.

"Login: Means that the shell is run as part of the login of the user to the
system. Typically used to do any configuration that a user needs/wants to
establish his work environment.

"Non-login: Any other shell run by the user after logging on, or which is
run by any automated process which is not coupled to a logged in user."
