(Optional) Become superuser or assume an equivalent role to terminate the process of another user.
Obtain the process ID of the process that you want to terminate.
$ ps -fu user |
where user is the user that you want to display processes for.
For example:
$ ps -fu userabc userabc 328 323 2 Mar 12 ? 10:18 /usr/openwin/bin/Xsun :0 -nobanner -auth /var/dt/A:0-WmayOa userabc 366 349 0 Mar 12 ? 0:00 /usr/openwin/bin/fbconsole userabc 496 485 0 Mar 12 ? 0:09 /usr/dt/bin/sdtperfmeter -f -H -t cpu -t disk -s 1 -name fpperfmeter userabc 349 332 0 Mar 12 ? 0:00 /bin/ksh /usr/dt/bin/Xsession userabc 440 438 0 Mar 12 pts/3 0:00 -csh -c unsetenv _ PWD; unsetenv DT; setenv DISPLAY :0; userabc 372 1 0 Mar 12 ? 0:00 /usr/openwin/bin/speckeysd userabc 438 349 0 Mar 12 pts/3 0:00 /usr/dt/bin/sdt_shell -c unset . . . |
The process ID is displayed in the first column of the output.
Terminate the process.
$ kill [signal-number] pid |
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.
Is the process ID of the process that you want to terminate.
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.
Verify that the process has been terminated.
$ pgrep pid |
The process you terminated should no longer be listed in the output of the pgrep command.
