Yes...

kill `ps -ef |grep process |awk '{print $2}'`

Or use UNIX95:

One problem with:

kill `ps -ef |grep process |awk '{print $2}'`

is, this will kill all processes that has the word
"process" in it's "ps -ef" output. This means, if you
are trying to kill a process named "roo", you will end
of killing all the root processes :-)

A better solution is:

# kill $(ps -e | grep " process$" | awk '{print $1}')

Note the black space in " process$" search string.

Actually, there is no better solution than to let ps find your processes by name. ps and grep is a very unstable way to locate processes by name because grep does not know where the process name is located and does a simple string match. The UNIX95 option will not only enable the -C option but also allow you to show just the fields you need for your script.

But we need additional information. Do you know the names of the two processes? Are these names the same or different? Will there always be exactly two of these processes or will there be one or many more?
