Recently I developed the habit of killing processes with
fuser -k -n tcp $PORT
which can hardly kill the wrong process. I prefer this over fiddling with a pidfile that may or may not be still there or may or may not contain the correct pid (OK, I am a bit dramatic here :-)
Yet the typical stop script I stumble over still uses a pidfile.
Am I missing an important feature of the pidfile approach or a misfeature of the fuser
approach. My best guess is that
fuser is not available. Though judging by search engine results, bsd, debian, suse, centos, aix, solaris all seem to have it.
