Patch Set 4: Code-Review-1

Supporting /usr/local/bin/dumpcap is important IMHO, the rest are nitpicks.

https://gerrit.osmocom.org/#/c/13253/4/ttcn3-tcpdump-start.sh
File ttcn3-tcpdump-start.sh:

https://gerrit.osmocom.org/#/c/13253/4/ttcn3-tcpdump-start.sh@5
PS4, Line 5: DUMPCAP=/usr/bin/dumpcap
Mine is in /usr/local/bin/dumpcap. Do we need to use the absolute path?


https://gerrit.osmocom.org/#/c/13253/4/ttcn3-tcpdump-start.sh@30
PS4, Line 30: /sbin/setcap
(might not be installed on all distributions there, I would have checked with "command")


https://gerrit.osmocom.org/#/c/13253/4/ttcn3-tcpdump-start.sh@37
PS4, Line 37: fi
How about telling the user why dumpcap is not used?

 else
 	echo "NOTE: dumpcap doesn't have cap_net_{admin,raw} (or 'setcap' is missing to check it), falling back to 'sudo tcpdump'."
 fi


https://gerrit.osmocom.org/#/c/13253/4/ttcn3-tcpdump-stop.sh
File ttcn3-tcpdump-stop.sh:

https://gerrit.osmocom.org/#/c/13253/4/ttcn3-tcpdump-stop.sh@35
PS4, Line 35:         DUMPER=`ps -q $(cat "$PIDFILE") -o comm=`
Consider replacing `` with $().

 DUMPER="$(ps -q "$(cat "$PIDFILE")" -o comm=)"
