A signal is a command sent by the operating system or by the user, to a program or process, forcing it to do something.
The "kill signal" forces a program to immediately "close" (terminate) regardless of what it is doing.
You should not use the "kill signal" unless the program has a problem or cannot end or close properly, because you will lose whatever it is working on.

What is Signal handling in Linux?
Signal handling is a programming concept that allows programs to talk to each other via 'signals'. A user can also issue signals to a program at will using the 'kill' command. For example, kill -15 <command> tells the command to terminate kill -9 <command> tells the command to terminate forcibly kill -USR1 <command> tells the command to do whatever it was programmed to do when it received the USR1 signal.
Use of 'kill'command in Linux?
The 'kill' command sends a signal to a given process. By default without any options it will send the TERM (terminate) signal. Other options may include the KILL signal which forcbly terminates a process without waiting. As far as USR1 and USR2 signals it depends on the kind of application that is in said process.
How do you kill a process with a particular PID?
Use the 'kill' command with the appropriate signal. If you just want to kill the process without regard to doing so in a graceful manner you can use the 'kill' command with a signal that all programs cannot ignore, such as: kill -9 12345 or kill -KILL 12345 for process 12345. Be careful, however, because if the process is updating files or databases this would corrupt the database. It is better to start with a more gentle approach, which is to try the hangup signal, then the interrupt signal, the termination or stop signal, and then finally the 'KILL' signal. Of course, if you know what the process is doing and don't care what happens when it is stopped, just use the 'kill -9' or 'kill -KILL' sequence.

What is the function of the kill command?
The 'kill' command is used to send a 'signal' to a process. The process is then free (for the most part) to interpret the signal as it wishes, assuming it is not a termination signal that cannot be ignored. A signal is an interrupt to the process; there are many signals that may be sent to a process or program.
