The first command shell was 'sh', the Bourne shell (Steven Bourne).
In an interactive shell session the shell program waits for the user to type in a command. When receiving a command the shell program will then attempt to locate it and process (execute) the command. You are interacting with the shell. Running a shell file requires a pre-stored series of commands stored in a file. Unless the shell program you are running is interactive then the shell executes each command in sequence, without involving the user at all.
1. For ubuntu the command is lpq 2. For redhat the command is lpstat
While the command is executing, the shell waits for the process to finish.
Both, all versions have a command line, and every version but minimal and server have a gui
The output would be 'shell shell' (without the quotes, of course)
