Explanation

Here we should use SIGTERM to terminate the process. When no signal is included in the kill command-line syntax, the default signal that is used is ?5 (SIGKILL). Using the ? signal (SIGTERM) with the kill command ensures that the process terminates promptly. However, the ? signal should not be used to kill certain processes, such as a database process, or an LDAP server process. The result is that data might be lost. Tip - When using the kill command to stop a process, first try using the command by itself, without including a signal option. Wait a few minutes to see if the process terminates before using the kill command with the -9 signal.
