If I'm asking questions regarding shell scripting. Where is the right place to do so? Is it Stackexchange original page or this?
Both are fine. Shell scripting is on topic and welcome on both SO and here. Which site you prefer is basically up to you.
Personally, and clearly this is a completely unbiased opinion, I would recommend you ask them here. SO gets thousands of questions per day, while we get less than 100. Your question is more likely to be noticed here.
