There isn't a concept of a 'default' shell in Unix; you may have a login shell specified by the system administrator for use when you log in. Although it isn't a fool-proof way to find your shell, you could use the command: echo $SHELL or use the 'finger' command to see what your default login shell environment is. You could also 'grep' for your information in the password file because the last field is your login environment shell.
It is the command interpreter: command.com
The a default Unix shell is the shell that comes with and is activated initially with your distribution of Unix. The shell is essentially the program the runs the command line interface allowing someone to interact with their computer. Some examples are the Bourne-Again shell (bash) or the Bourne shell (sh).
That would be a semi-contradiction; the command line would need to be already running in order to enter a command. The name of the program that actually provides the command line is called a shell. There are many different shells available for Linux, including Bash, ash, C Shell, fish, ksh, zsh, and scsh.The default command shell is /bin/sh (not /bin/bash, note).
The 'who' command merely tells you the users that are logged in and when they logged in. It doesn't give any more information. The default shell for Unix can be different for different users; if you are talking about the login shell, then you can find out the login environment for users by either using the 'finger' command on an individual user, or looking at the /etc/passwd file. It will be the last field on each line for each user.
There is no such thing. The "default shell" is a decision made by the distributor.
Up to DebianLenny, the default /bin/sh shell was bash. Starting with DebianSqueeze, the default shell will be dash.
There is no "default" Unix shell. Different Unix vendors shipped different shells.
The default user shell is set in the password file as an entry for each account.

There is no "default" shell. Different distros are free to pick whatever shell they want. The most commonly used as the main shell is Bash, but other shells, including the Korn shell, C shell, Friendly Interactive Shell, or Almquist shell are also available. Many distros also use a variant of the Almquist shell provided by BusyBox in their initial ramdisks before switching to the real root and launching the main shell.
