shell

Shell:
You interact with unix using a special program called Shell. IT passes to commands to the Unix operating system.
It comes in different flavours: bash, Bourne shell(sh), C Shell(csh) etc.
Each shell uses a particular character (or string of characters) to prompt the user for commands; not surprisingly, this is known as a shell prompt. Exercises in this tutorial show the default shell prompt for csh, the "%" character.
