I was about to flag this question about modifying terminal behaviour as off-topic because I thought it really belonged at Ask Ubuntu (or Unix & Linux, since the issue actually applies more generally to Linux). But then I thought maybe it is actually on-topic here, as the Linux terminal could be considered a "software tool commonly used by programmers". Is such a question on-topic or not, and why?
I'd say that question is off-topic, but it's too old to migrate to another site so I just closed it.
The Linux terminal could be considered a "software tool commonly used by programmers," but it is by no means primarily a programming tool, and I don't see any evidence in that question that the author was using it for programming. It would have been better asked on Ubuntu or Unix & Linux as you suggested.
