Tumblr aside, &quot;kill&quot; is a dumb name anyway. It just send signals, and it&#x27;s default signal isn&#x27;t kill, it&#x27;s terminate. And hangup doesn&#x27;t have anything to do with terminating.<p>A better name would have been &quot;signal&quot; (as in the verb), avoid a default signal (how often do you actually send TERM?) and to use lowercase for the signal names consistent with other commands.
