ok i hate to sound like a complete lamen, but could you spell it out for me a bit better than that for me please. I am a complete beginner and dont really know much about it.
It's easier to understand when you format your code so that's more manageable to work with and read ...
The select statement reads the values after 'in' ... "blabla" "blabla" "quit" .
Then selects each one in turn and passes the value to $action to use within the select statement. $action is used in the case statement, here the value is compared to those listed values contained within the case statement and if a match is made, executes the code attached to that match. If the value of $action doesn't match any value contained within the case statement, then it is passed to (or rather picked-up by) the statements associated with '*'.
Very new to the Korn Shell, but I've been looking up loops online and it seems this should work. I'm just trying to convert an ip range in variables $A and $B and iterate the individual ip's out to new lines. Unfortunately I get {152..155} instead of 152, 153, 154, and 155.

I'm trying to understand if it's possible to create a set of variables that are numbered based on another variable (using eval) in a loop, and then call on it before the loop ends.
