You have been asked to terminate a process that appears to be hung and will not terminate. The process table is shown below: root 15163 15156 0 12:51:15 pts/3 0:00 hungscript What command will terminate the process? 

Answer options:

A. kill -9 15163
B. kill -1 15163
C. kill -15 15163
D. kill -2 15163

A

Here we should use SIGTERM to terminate the process. Note: When no signal is included in the kill command-line syntax, the default signal that is used is 15 (SIGKILL). Using the 9 signal (SIGTERM) with the kill command ensures that the process terminates promptly. However, the 9 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.
