Is there any command, or any simpler way to get the full list of\u00a0all<\/em>\u00a0descendant processes?<\/p>\n\n\n\n Active<\/a>Oldest<\/a>Votes<\/a><\/a>20<\/a><\/p>\n\n\n\n The following is somewhat simpler, and has the added advantage of ignoring numbers in the command names:<\/p>\n\n\n\n Or with Perl:<\/p>\n\n\n\n We’re looking for numbers within parentheses so that we don’t, for example, give 2 as a child process when we run across So I also think that process groups are the way to go. If you’d like to have a process run in its own process group, you can use the ‘pgrphack’ tool from the Debian package ‘daemontools’:<\/p>\n\n\n\n Or you could again turn to Perl:<\/p>\n\n\n\n The only caveat here is that process groups do not nest, so if some process is creating its own process groups, its subprocesses will no longer be in the group that you created.Share<\/a>Improve this answer<\/a>Followanswered Jul 14 ’13 at 19:01<\/a>Jander<\/a>14.7k<\/strong>55 gold badges4343 silver badges6565 bronze badges<\/p>\n\n\n\n8 Answers<\/h2>\n\n\n\n

But if the command name contains a parenthesized number, all bets are off. There’s only so far text processing can take you.<\/p>\n\n\n\n pgrphack my_command args\n<\/code><\/pre>\n\n\n\n perl -e 'setpgid or die; exec { $ARGV[0] } @ARGV;' my_command args\n<\/code><\/pre>\n\n\n\npstree -lp | grep -Po \"(?<=\\()\\d+(?=\\))\"<\/code> \u2013 puchu<\/a> Mar 13 ’18 at 21:48<\/a> <\/li><\/ul>\n\n
