i will correct myself:

'search' will have a null value and my code should be
Code:
if [[ "$search" = "" ]]

Not sure if I got your problem right yet, nevertheless:

Code:
if [[ -z "$search" ]]

So you can check if there is a parameter or not and do the actions needed. The problem with the value assigning to a variable and all the double quotation marks etc. is solved?

Just to wrap it up, I note that you are missing the closing fi from the if conditional. (I'm sure you did that on purpose; just to straighten this out for any future readers of this thread.)

The [[ test command is available in POSIX shell I believe, but not in "classic" Bourne shell.
