How to send signals to processes (e.g., terminate) in Bash?

In Bash, you can send signals to processes using the kill command. The syntax for sending signals with kill is as follows:

Here, PID refers to the process ID of the target process.

To terminate a process gracefully, you can use the SIGTERM signal. To send this signal with kill, you can use the following command:

Replace PID with the actual process ID of the process you want to terminate.

If you want to forcefully terminate a process, you can use the SIGKILL signal. To send this signal using kill, you can use the following command:

Again, replace PID with the actual process ID.

There are also other signals available, such as SIGHUP, SIGINT, SIGSTOP, etc. You can specify a different signal by using the -<signal> option with kill command, for example:

Make sure to replace PID with the actual process ID and SIGHUP with the desired signal.

Note that you need appropriate permissions to send signals to processes. In most cases, you either need to be the owner of the process or have root/administrator privileges to send signals to other processes.
