Modifying the Bash Shell
A Linux system administrator should have a solid understanding of the Bash shell environment. The Bash shell is the default command line interface used on the vast majority of Linux distributions. Linux administrators can extend the capabilities of the Bash shell by providing their own aliases to commonly used commands and options, as well as create their own functions to use in the Bash environment. In this hands-on lab, we will create our own alias for a command and then create a new command that will take a positional argument.
