The bash shell has simple variables and one-dimensional array variables. That one is simply creating an empty array.

You can see the effect in the following transcript which creates arrays of varying sizes and shows you their size:

pax> x=(1 2 3 4 5) ; echo ${#x[@]}
5
pax> x=(1) ; echo ${#x[@]}
1
pax> x=() ; echo ${#x[@]}
0

@Axit, I'd prefer you to accept my answer because it was right rather than quick but, since it's both right and quick, I'll take it :-)

i first checked that it was right or not. and then i commented like this. as Stackoverflow only allows to accept answer after 15 mins. :)
