How to take arguments?
Hey everybody.

How do you write a program that will produce output based on its arguments?

For example, how would you write one that will add 1 to an integer argument so it would look like this:
Code:
$add 1 78
79
$

I only know how to write programs to take user input with the read function, which doesn't read arguments, only input on a separate line.

Thanks

Arguments are $1 $2 $3 ...

Code:
$ cat pgm
echo $(( $1+1 ))
$ pgm 78
79
