Hey I tried a tutorial's example and I can't make it work
Q.5.Modify above and store division of x and y to variable called z
For Ans. Click here
$ z=`expr x / y`
$ echo $z
Oh wait, I made it work. That's not a single quote, that's that crazy backquote character by the 1 key.
Okay but I still have to do this:
$ z=`expr $x / $y`
His example doesn't use the $ signs. Why?
