How to clear the current command line in Linux or Mac terminal?
For example, if you typed a bunch of instructions wrongly, and you want to clear them,
Be sure to do the same as I used to, use the reverse key to kill slowly, we can use ctrl+u
Remove the entire command line directly.
If you press ctrl+u to delete the entire line command,
If you want to restore , you can press ctrl+y .
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 think most of the current Linux supports Access Control List (ACL). With filesystem ACLs enabled, We can set additional permissions to different users or groups. This allows us to set the file system permissions of different users more freely. Go straight to the command.
Detect whether selinux is enabled in the system
