问题 Basically I want to dynamically start some processes which may create their own children processes, also I want to kill a certain group of processes I just created whenever I want. One way I could think of is to start processes with a name(to distinguish as a group), then use pkill to kill them by the name. The question is how to start a process with a name so that I can use pkill to kill them by the name? I am open to other solutions as well. 回答1: There is very similar question on

问题 The usefullness of task killer apps is debated, but I'm wondering: how do they actually work? How is it possible to kill particular process?

时光怂恿深爱的人放手 提交于 2019-12-08 02:04:00
问题 I've got a Perl script that starts a background job to print some logging information into a file, executes something, and then finishes. I would like to end the background process when the script is done, but as far as I know, if I use a double fork as below, then waitpid($pid,0) will wait for the background process to finish, instead of killing it, and kill(9,$pid) won't get rid of the background process.
