how do I run a shell command?

It looks like the book is wanting you to put that text in a text editor, and save the file as a shell script (*.sh).

You would then open a terminal window and type: sh command.sh to execute the command.

HTH.

Thanks for the advice. All of them I need to copy and paste it on the text editor then save it there? Sorry I am slow please explain it at the beginning so I can practice it again. But how do I run it? Do I run from text editor or run it on the terminal?

I'll try one more time.

Open up the text editor of your choice. Paste the following into the empty file:

#!/bin/bash
echo Select a country from the following list:
echo America, Italy, France, Germany
read country

case $country in
  [Aa]merica ) echo Ford; echo Perhaps;;
   [Ii]taly ) echo Ferarri;echo no;;
   [Ff]rance ) echo Peugeot ;echo no way;;
   [Gg]ermany ) echo Porsche ;echo yes;;

esac

Now, save that file as command.sh

Close the text editor.

Open up a terminal, and navigate to the directory where you saved 'command.sh'

in the terminal type: sh command.sh

Answer the question, and you'll get an output.

Hi Jayson,

Thank you very much. I am doing it backwards that's why it's not working. Now, I know that I need to start at the text editor then terminal. I will try it now. I really want to learn Linux because I found it very very interesting but I really need to do a lot of practice and readings so I can get familiar with it. It's really when I don't have that programming skills. : )

Does anybody know why this "[Aa]merica )" is in both caps and lower case from the sample above?

To match both America and america cases . It's a small regexp.

Thanks. On the previous problem. I followed Jayson instructions step by step but when I opened terminal, typed sh command.sh , it doesn't want to run. I don't know what I am doing wrong.

Thanks but it didn't work. I tried something else and it worked. Instead of using chmod 700 command.sh , I put chmod +x command then execute it. Thank you for the three of you helped me figure this out. THANKS A LOT GUYS.
