Two ways :
1) Put your commands in nested if ... then ... fi statements.
2) Chain your commands with && like
Code:
command1 && command2 && command3
# Is similar to
if command1
then if command 2
       then command3
       fi
fi

That will return "0" only if the 3 commands executed successfully. The other thing is that command2 will only be executed if command1 executed successfully, and so on. It's almost preferable to avoid executing a command if the previous operation didn't succeed.
