Ps is a very important system tool that can be used to view the current processes in the system.

Man ps

Report a snapshot of the current processes.

That is to say, what components are active in the ecosystem of a system. Similar to the Job Manager in windows.

When using ps, we often find that both the minus sign and the minus sign can be run. In fact, the minus sign is in the linux format, and the difference is in the BSD format, which is compatible.

In an ecological environment, various processes (threads) are running and acting. This process is a tree structure. The root is init.

Commonly used include ps, pgrep, and pstree.

For example, if you want to see how many processes are running in apache, you can use pstree to see that 10 processes are running.
