This is really not a great shell coding best practice but

Code:
somecommand arg1 || somecommand arg1

executes somecommand1 an additional time if it fails the first time.

This will NOT work with pipes i.e., command1 | command2 because the status returned is from the rightmost element in the line, but others may fail. Some implementations have a workaround for this problem.
