A few problems there.

Code:
x=o

Did you mean zero?

Code:
while [ x -ne 2 ]

You've got the right idea, and the right syntax, but you're giving it the string "x", not the contents of the variable. Use "$x".

Code:
x++

Shell math doesn't work this way. If you have bash or ksh:
Code:
((x++))

otherwise do this:
Code:
x=`expr $x + 1`
