Well, first up it sounds like a bug in swatch. Report it! You could try to find out if swatch is in its own process group. If you started it from an interactive shell, or it is in its own terminal "stand alone", as it were, then this is probably true. Evn more helpfully, it is probably the process group leader, so the number of the process group is the same as swatch's pid. Just as you kill a process with kill -s 15 pid-number you can kill a process group with a negative number. kill -s 15 -pgroup-number ... but ... you need to disam You need to use "-s signal' instead of "-signal" because otherwise the "-pgroup-number" looks like a signal. Example: kill -s 15 -1234 to kill process group "1234" with signal 15 (SIGTERM, the default signal).
