Bash - looping over .ssh/config and execute traceroute which stops after 25 seconds. Could be enhanced by highlighting traceroute results for certain greps.

sshloop.sh

#stop script by: CTRL C and also "pkill traceroute"

while IFS="" read -r p || [ -n "$p" ]
do
  if [[ "$p" =~ ^Host.* ]];
  then
    printf '%s\n' "$p"
      if [[ "$p" =~ ^Hostname.* ]];
      then
        traceroute "${p/Hostname /}" &
        TASK_PID=$!
        echo $TASK_PID
        sleep 25
        kill $TASK_PID
        printf "\n\n\n\n"
      fi
    fi
done < .ssh/config
