In the previous activity you created several aliases and saved them to your ~$/.$bashrc file.

You may have noticed that creating long strings of commands can get a bit cumbersome when working on the command line.

Instructions

Complete the following set$-$up:

Create a new script file called sys$\_$info.sh$.$

Your script should output the following data:

A title and today's date.

The uname info for the machine.

The machine's IP address. $($Narrow this output down to one line.$)$

The Hostname.
