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?
Correct Answer: A
Explanation/Reference:
Explanation:
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.
