Linux查看进程的所有子进程和线程

得到进程的pid：

ps -ef | grep process_name | grep -v "grep" | awk '{print $2}'

查看进程的所有线程

# ps mp 6648 -o THREAD,tid

USER %CPU PRI SCNT WCHAN USER SYSTEM TID

root 0.0 - - - - - -

root 0.0 24 - - - - 6648

root 0.0 21 - - - - 6650

root 1.0 24 - - - - 14214

root 0.0 23 - futex_ - - 14216

root 0.0 22 - 184466 - - 15374

root 0.0 23 - 184466 - - 15376

root 0.0 23 - 184466 - - 15378

root 0.0 23 - 184466 - - 15380

root 0.0 23 - 184466 - - 15392

root 0.0 23 - 184466 - - 15394

root 0.0 23 - 184466 - - 15398

查看所有子进程：

# pstree -p 6648

agent_executor(6648)─┬─tar(15601)───gzip(15607)

├─{agent_executor}(6650)

├─{agent_executor}(14214)

├─{agent_executor}(15378)

├─{agent_executor}(15380)

├─{agent_executor}(15392)

├─{agent_executor}(15394)

└─{agent_executor}(15398)
