I cannot find them anywhere on the internet or in my ebook from my class, so I'm stumped. Here they are:

Choose one of the Ubuntu shells and discuss how you can perform a minimum of 20 commands or functions. These commands must include command-line utilities and scripting techniques for automating operating system tasks, including enterprise deployment.

I chose Bash as my shell and I hope that's right, so can it please be done based on Bash?

Thank you...
