From Step $4$ onwards, write the correct commands in your script file. You can open your script simply by

double clicking it$,$ which should open it in Emacs $($or the default editor if you haven$$t installed Emacs$).$

Remember that you can execute your script by first making it executable $($you only need to do this

once$)$:

$chmod $+$x script.sh

And the following in the command:

$bash myfirstscript.sh

Or you could add a shebang line in your script to execute it by running:

$$./$script$.$sh

Experiment with both approaches and use the one you feel the most comfortable with. From a

professional standpoint, I think that using the shebang line is better. Then, write the necessary

commands in your script to do the following:

$4.$ Create a directory called big$-$directory.

$5.$ Inside big$-$directory, create another directory called small$-$directory.

$6.$ Create a file in small$-$directory called file$-1.$txt$.$

$7.$ Write your name in file$-1.$txt$.$ You can use the echo command alongside redirection.

$8.$ View the contents of file$-1.$txt$.$

$9.$ Append the numbers from $1$ to $20$ to file$-1.$txt$,$ one number per line.

$10.$ View the contents of file$-1.$txt$.$
