HrrmMm..
Question: I just started learning shell scripting a few days ago and I was under the assumption that you didn't need to typeset anything.
One of my previous counters looked like this (in a while statement, not an if statement:
var1=`expr $var1 + $var2`
..and it worked.
But when I tried the expr command in the if statement, it didn't increment at all. Would you know why this is? Could it be because once you enter an if statement, you must use different rules?
