To kill a halted, frozen, or resource-consuming application on a Linux or Unix system, you can use the kill command. The kill command sends a signal to a process, which can be used to terminate the process.
Here's the basic syntax for the kill command:
kill pid
pid is the process ID of the process that you want to kill. You can find the process ID of a process using the ps command or the pgrep command.
ps aux | grep process-name pgrep process-name
Once you have the process ID, you can use the kill command to send a signal to the process. By default, the kill command sends the SIGTERM signal, which terminates the process.
kill pid
If the process does not respond to the SIGTERM signal, you can use the -9 option to send the SIGKILL signal, which forcibly terminates the process.
kill -9 pid
It's important to note that the kill command can only be used to terminate processes that are owned by the current user. If you need to terminate a process that is owned by a different user, you will need to use the sudo command to run the kill command with superuser privileges.
sudo kill pid
Overall, the kill command is a useful tool for terminating halted, frozen, or resource-consuming applications on a Linux or Unix system. By using the kill command, you can easily terminate processes that are causing problems on your system.
