Kill any Linux process from any UID
The kill command in the linux systems are used to terminate any process that is currently running. The kill command sends a TERM signal to the process. The kill command takes in the process ID of the process that needs to be stopped along with some additional parameter that specifies additional constraints. To kill all the process that is running give the command kill -9 -1. If you cannot kill a process from your id login as root by using the su command and typing the root password. But you cannot kill a process that you are not allowed to if else it would lead to the security hole in the linux systems.
