-The terminate signal will kill processes that do not catch the signal;
-`kill \-9 ...' is a sure kill, as the KILL (9) signal cannot be caught.
-By convention, if process number 0 is specified, all members
-in the process group (i.e. processes resulting from
-the current login) are signaled (but beware: this works only
-if you use
-.IR sh (1);
-not if you use
-.IR csh (1).)
-The killed processes must belong
-to the current user unless
-he is the super-user.
