Edit Question
Title
Body
Believe it or not, I can't find the answer to what I would think would be this very basic question. In awk, how can I loop over the input string character by character? Let's say I just wanted to print them out. Is there an array I can access? Or do I need to use substr? Basically, something like: echo "here is a string" | awk ' { for(i=0; i<[length of input string]; i++) printf [value at index i in array x]; }' Frankly, I'm embarrassed.
