How to Kill a Process Without a PID Number
- 1). Open a terminal or log in to the computer via an SSH session.
- 2). Type the command "su -" to become the root user. If the process has been started by you, using your own user account, you can skip this step.
- 3). Type the command "pkill process_name" to kill a process using its name. Replace "process_name" with the name of the process. For example, type "pkill firefox" to stop all instances of the Firefox Web browser.
- 4). Type the command "exit" to close the root session.
