 Which is probably the wrong way to "fix" this.

 The most likely reason for the "unary operator" message is that
$revision has no value, making the statement

 if [ = "1" ]

 I'm guessing here, but one possible solution is to make the line

 if [ "$revision" = "1" ]

hence ensuring you have an empty STRING on the left, and not a missing
argument. IE:

 if [ "" = "1"]


 The REAL fix is to find out why the variable revision has not been set
to a value!
