I ran that command on both bash 4.4 and 5.1, and checked PGIDs using pstree; results were parallel:
$ pstree -pg 3255 # 4.4 bash(3255,3255)───bash(3296,3296)───sleep(3297,3255) $ pstree -pg 3299 # 5.1 bash(3299,3299)───bash(3305,3305)───sleep(3306,3299) Are you sure a misplacement of the child is the issue here? Or am I missing something?
