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