Write a very simple script to test out the command line and to refresh your Linux

knowledge from prior classes. Here are some sample steps:

a$.$ Open a file with the nano editor with your choice of filename and the sh extension

for Bash: nano $.$

b$.$ Enter the #$!/$bin$/$bash directive $($the shebang$)$ on the first line to indicate the bash

shell.

c$.$ Type in some sample built$-$in commands such as whoami, pwd$,$ date, and then,

print a unique string to the screen using echo.

d$.$ Save and exit your file using the options at the bottom of the editor.
