How to Terminate a Process With the pkill Command - Managing System Information, Processes, and Performance in Oracle® Solaris 11.4

Language:

() To terminate a process that you do not own, assume the root role.
Obtain the process ID for the process that you want to terminate.
```
# pgrep process
```
For example:
```
# pgrep firefox
587
566
```
The process ID is displayed in the output.
Terminate the process.
```
# pkill [signal] PID
```
signal

When no signal is included in the pkill command-line syntax, the default signal that is used is -15 (SIGKILL). Using the -9 signal (SIGTERM) with the pkill command ensures that the process terminates promptly. However, do not use the -9 signal to kill certain processes such as a database process or an LDAP server process because data might be lost.

PID

The process ID of the process to terminate.

Tip - When trying to terminate a process, first try using the pkill command by itself without including a signal option. If the process does not terminate after a few minutes, use the pkill command with the –9 signal.
Verify that the process has been terminated.
```
# pgrep process
```
The process you terminated should not be listed.
