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.

What is kill signal in Linux?

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.

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.
