On CentOS 7, you can use the `ps` command to view processes. Here are some common `ps` command options:

ps aux：显示所有用户的所有进程。

ps -ef：显示所有进程，包括父进程ID（PPID）和程序的启动命令。

ps -eLf：显示详细的线程信息。

ps -eo pid,ppid,cmd,%mem,%cpu：显示指定字段的进程信息，如PID、父进程ID、命令行、内存占用和CPU占用。

In addition to using the `ps` command, you can also monitor processes in real time using the `top` command. It displays a list of currently running processes sorted by CPU usage and you can exit the `top` command by pressing the `q` key on your keyboard.

Please note that the commands `ps` and `top` require sufficient permissions to view all processes. If you are a regular user, you may need to run these commands as root or use `sudo`.
