unix scripting

Comment:

Hi, I'm having problems with unix script programming. I need to be able to write a basic addition expression, and be able to read values from a command line like ./add 3 4 5. Thankyou.

In Korn shell you define arithmetic expressions within double round brackets, e.g: integer x=1 y=2 z=3 (( x = y + z )) (( x += y )) print $x + $y = $(( x + y )) Hope that helps.
