How can you terminate processes in Ubuntu?

In Ubuntu, there are several methods to terminate a process:

1. To use the kill command, first you need to locate the Process ID (PID) of the process you want to terminate. You can use the ps command to view the currently running processes and their PIDs. Then, use the kill command with the PID to terminate the process. For example, to terminate the process with PID 12345, you can run the command: kill 12345.
2. The killall command can be used to end multiple processes based on the process name. For example, to end all processes named “firefox,” you can run the command: killall firefox.
3. Use system monitoring tools: Ubuntu provides several system monitoring tools such as System Monitor and htop. These tools allow you to view running processes and provide a graphical interface to end processes. You can find and open these tools by searching for “System Monitor” or “htop” in the application search bar.

It is important to note that terminating a process may result in data loss or system instability, so please use caution. Before ending a process, it is recommended to first try resolving the issue through other means, such as restarting the application or system.
