BTW 2>&1 does not make sense in this context (it's a redirection of error
message of EXPECT_PASS function, which would be to stdout.
I also noticed this part of traceroute01.sh is also wrong:
EXPECT_PASS traceroute $ip $bytes -n -m 2 $opts \>out.log 2>&1

It should be:
EXPECT_PASS traceroute $ip $bytes -n -m 2 $opts \>out.log 2\>\&1

But IMHO it'd be better in both cases to keep stderr not redirected
(don't hide problems). Therefore, unless you're against it, I'll remove
redirection from traceroute01.sh.

Kind regards,
Petr
