bash question

[Chuck Hallenbeck]

If all you want to do is check if it has returned zero or nonzero, you
can use the if-then-else construct, like this:

if command arg1 arg2 ...
then
action1
else
action2 
vi

The first action is on success, the second action is on an error value
returned from command.
