You can use the commandps auxfto view a hierarchical tree of all running processes. Once you have obtained the PID or process name, usekillallorkillto terminate the process as above. Another option to find the
如果有任务需要处理时,遍历工作链表,对链表中的每个节点调用 process_one_work 来执行 work 的回调函数,即 INIT_WORK 里的回调函数。 sleep 中,没有任务处理时,worker 进入空闲状态,并将当前的内核线程设置成睡眠状态,让出 CPU。 总结
such as if and other control-structure openers, function, {, or (, then the command is actually a compound command. The shell sets things up internally for the compound command, reads the next command, and starts the process again. If the keyword...

-n. Return the newest process. -o. Return the oldest process. -u. Only find processes that belong to a specific user. -x. Only find processes that exactly match the given pattern. For example, the commandpgrep -l -u rootdisplays the names and PIDs of all processes owned by root: ...
