\nSIGKILL (9)<\/b> \u2013 Kill signal. Use SIGKILL as a last resort to kill process. This will not save data or cleaning kill the process.<\/p>\n


<\/b><\/p>\n

\nSIGTERM (15)<\/b> \u2013 Termination signal. This is the default and safest way to kill process.<\/p>\n


<\/b><\/p>\n

\nThe difference between 9 and 15 is, the default action for both of them is to terminate<\/p>\n

\n the process, but 9 can’t be caught or ignored. So if signal 9 gets sent, the process is <\/p>\n

\nguaranteed to die, immediately. If a sig 15 is sent, the process can catch it and perform cleanups.<\/p>\n
