unable to execute while loop
Hi everyone.

I wanted to print numbers from 1 to 5 in reverse order. For this I used the following code:
Code:
#!/bin/bash
x=5
while [$x -ge 0]
do
        echo $x
        x=`expr $x - 1`
        echo ""
done
echo ""

Well but on compiling the above code, it gives the following error.
Code:
num_while.sh: line 5: [5: command not found

Can anyone please help me out in this regards?

Thank you.
