Aaron LI c362781c8d timeout(1): Document the reaper implementation and behaivor ... If timeout(1) runs with the --foreground option, it becomes the reaper of the command and its descendants and will wait for all of them to terminate. This behavior is different from the old FreeBSD version and GNU version. For example, if there is a descendant running in the background, like: $ timeout -s INT 2 sh -c 'sleep 4 & sleep 5' when timeout(1) sends the SIGINT to all descendants, the child 'sh' process and the foreground 'sleep 5' process will immediately terminate, but the background 'sleep 4' will be reparented to the timeout(1) itself. Because a background process ignores SIGINT and SIGQUIT, the whole command completes until the background 'sleep 4' finishes. In comparison, the old FreeBSD version and GNU version will just terminate itself, letting the background 'sleep 4' process be reparented to an upper reaper like init. The POSIX.1-2024 standard doesn't specify the required behavior in such cases, so I decided to keep the current implementation. Nonetheless, the updated timeout(1) has changed a lot in order to conform to the standard. Obtained-from: DragonFly BSD		2025-04-16 21:45:38 +02:00
