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.
