Shell Scripting

Asked by zelenytsya on 2012-04-20

Hi. I have a shell script with the following lines:

#!/bin/sh
echo "I will work out X*Y"
echo "Enter X"
read X
echo "Enter Y"
read Y
echo "X*Y = $X*$Y = $[X*Y]"

and result:

petro-z@petro-z-desktop:~$ ./myfile.sh
I will work out X*Y
Enter X
2
Enter Y
3
X*Y = 2*3 = $[X*Y]

where 6? or how receive 6?
