At the end of the article "using an independent PID namespace to prevent mistaken killing processes", I encountered a problem, that is, the process in the parent PID namespace cannot use the PID value written through ECHO $> $ pidfile into the

In the Linux top and PS commands, the default is to see the PID (Process id), perhaps you can see the LWP (thread id) and Tgid (thread group ID for the thread group leader), and so on, while the Li Nux library functions and system calls maybe you

  Cause: During the deployment of Java programs over the past few days, I found that every time I restart the Java app, I have to first Ps out the process ID and then kill it to kill the process, however, if the server only deploys one or two Java
