Why was "Why is `ls -al & ; ls -al` invalid?" closed as "off-topic" by a moderator, with precisely zero community votes to that effect?
The previous concensus appears to be (example) that Bash "programming" is on-topic on Stack Overflow. I struggle to find a way to use Bash without programming, though.
It seems a shame that once again I must come to meta to find community concensus on the issue, because the original mechanism to apply community concensus (that is, voting) has been overridden! [edit: I forget that flags can lead to this outcome. Still. That's why I don't like that flags can override the voting mechanism.]
Never mind; @BoltClock has re-opened it.
I guess that settles that!
