A very simple explanation of how && works: do this command:

ls && ls /wrongdir && ls

Then do this command:

ls && ls && ls

You will see that in the first case the failure of 'ls /wrongdir'
prevented execution of last 'ls'. That's how && works. The next
command is executed only if the previous one was a success.

cheers
