Tal vez sh no está apuntando a bash, acá me funciona perfecto:

$ wget http://www.bashcookbook.com/bashinfo/source/bash-4.0/examples/scripts/timeout3
$ chmod +x timeout3
$ date; sudo ./timeout3 -t 3 tcpdump -ni l0 ; date
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on l0, link-type NULL (BSD loopback), capture size 65535 bytes

0 packets captured
0 packets received by filter
0 packets dropped by kernel
