"Command not found" doing a while loop in bash/shell
Code:
i=0
numberofproducts=${#urls[@]}  #gets number of entries in array called "urls"
numberofproductsminusone=`expr $numberofproducts - 1`   #-subtract by one

while [$i -lt $numberofproducts]
do
	wget ${urls[$i]}
	 i=$(( $i + 1 ))
	sleep 10
done


I'm getting an error

./scrape: line 22: [0: command not found


that line corresponds with the "while" line.

Could anyone help me with this ? I googled but none of the examples I found were relevant to this.
