What would you like to do?
When you can't install the mtr utility, but need to determine on which hop your datagrams are being lost
DIR="$(mktemp -d /tmp/ping_XXXXXXXX)"
echo "Results will be stored to the ${DIR} directory"
for HOP in $(traceroute -n "${HST}" | sed -nr 's/^[[:space:]]*([[:digit:]]+)[[:space:]]+([[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3})[[:space:]]+.*$/\1:\2/gp'); do
IFS_OLD="${IFS}"; IFS=":"; read -a ARR <<< "${HOP}"; IFS="${IFS_OLD}"
ping -c "${CNT}" ${ARR[1]}" > "${DIR}/pingtrace_${ARR[0]}_${ARR[1]}" &
echo -n "Waiting for ${CNT} packets to be sent..."; sleep "$((CNT+3))"; echo "OK!"
grep "transmitted" "${DIR}"/*
