What happens when you assign to $0?
According to git log
I've submitted 33 patches to perl core, I just submitted another one which on Linux changes this:
Into this:
If this patch gets applied doing killall onion
on 5.14 will get you a dead process instead of onion: no process found
, the same goes for ps(1)
and top(1)
which read the legacy process name by default. Before this patch the behavior of $0 assignment on Linux hadn't changed since perl 4.000 came out.
