"From the end user's perspective, the shell is the most important program on the Unix system because it is the user's interface to the Unix system kernel. The shell reads and interpreting strings of characters and words."
"The shells operate in a simple loop:
1.Accept a command
2.Interpret the command
3.Execute the command
4.Wait for another command"
"The shell displays a prompt, notifying the user that it is ready to accept a command. It would be nice if you could speak or type instructions into the computer in some form of natural language."
OK, Hal. Sort out my correspondence, throw out anything that is too old, and archive the rest.
"Unfortunately, the shell recognizes a very limited set of command words, so the user must offer commands in a way that it understands. This means learning to string odd words and punctuation together."
