Detect whether selinux is enabled in the system
For Linux system administrators, you must understand the ps aux command. If you want to be a Linux system administrator, or you are a Linux user, you should understand this command. ps is process status For short, anyone can find out what kind of program is running on the system and how the status is executed through this command. I saw some programs that should not appear, maybe the system was hacked and used to mine🥹
I have some audio files downloaded from Youtube that I want to play in the background, do I know how to do it?
