Week 3 – Advanced file management utilities and quoting

I. File name expansion: File name expansion, also known as globbing, is a feature in the Unix shell that allows you to specify a group of files using wildcards. Wildcards such as * and ? can be used to match one or more characters in a file name, making it easy to perform actions on multiple files at once.

II. Command execution in detail: This section could delve deeper into the details of how commands are executed in the Unix shell. It could cover topics such as command parsing, command search and execution, and the PATH environment variable.

III. Command history: The Unix shell has a built-in command history feature that allows you to recall and execute previous commands. This section could cover how to view and manipulate the command history, as well as how to customize the command history behavior.

IV. Recalling and editing previous commands: This section could cover techniques for recalling and editing previous commands, such as using the up and down arrow keys to navigate the command history, and using the vi editor to edit previous commands.

V. Quoting: Quoting is a way to treat special characters in the Unix shell as literal characters, rather than as special symbols. This section could cover the different types of quoting available in the Unix shell, such as single and double quotes, and how to use them to protect special characters from being interpreted by the shell.”
