This recipe is useful when one wants to kill all the processes belonging to one user or having a particular regular expression in the process name.

One can use different options of “ps ” and “grep ” to kill the undesired process(es).

The following is the general syntax of this recipe

ps -u | grep

| awk {print $1} | xargs kill -9

ps -u

will find all the processes of the user username.

This output is then greped for processname_pattern which is then piped to awk

awk ‘{print $1}’

will print only the first column of the output (the process-id, in this case).

This is then xargd to the kill with sure kill -9 signal.

As a result,all the undesired processes will be killed.

Note : One should give the processname_pattern carefully as an incorrect

regular expression may lead to even desired processes being killed.
