You can list processes in Linux using commands like ps, top, htop, atop, and pstree. Each provides a different output format, from static snapshots (ps) and real-time monitoring (top and htop) to historical logging (atop) and process hierarchy views (pstree). How do I see all running...

U userlist Select by effective user ID (EUID) or name. This selects the processes whose effective user name or ID isinuserlist. The effective user ID describes the user whose file access permissions are used by the process (see geteuid(2)). Identical to-uand--user. -Uuserlist Select b...

Additionally all of the processes in the system are held in a doubly linked list whose root is theinitprocessestask_structdata structure. This list allows the Linux kernel to look at every process in the system. It needs to do this to provide support for commands such aspsorkill. ...
1. 在调用fork函数之后,当执行的程序代码转移到内核中的fork代码后,内核需要分配新的内存块和内核数据结构给子进程,内核数据结构包括PCB、mm_struct和页表,然后构建起映射关系,同时将父进程内核数据结构中的部分内容拷贝到子进程,并且内核还会将子进程添加到系统进程
