Why is the name of the system call kill () a misnomer?
What will be an ideal response?
The kill command actually sends a signal to a process. Any signal can be specified, but by default,
the signal that is sent is a SIGTERM signal. SIGTERM tells a process to terminate, effectively
acting as a process killer. The kill command was probably named this way because killing a
process is the most common use of the command, so in many cases the name makes perfect sense.
Consider the case, however, where you send a USR1 (user-defined) signal to a running process
because it will trap the signal, do some special processing, and then return to what it was doing
before the signal was sent. In this case, you really aren’t killing the process, you are simply
sending it a message.
