Section 7/10 of Introduction to Bash Scripting may contain a logic issue in this loop:

for ip in "10.10.10.170 10.10.10.174 10.10.10.175"

do

ping -c 1 $ip

done

Because the IP list is wrapped in quotes, wouldn’t Bash treat it as a single loop item rather than three separate IPs?

That would seem to expand into one command using the full string, instead of pinging each address individually.

Should it instead be:

for ip in 10.10.10.170 10.10.10.174 10.10.10.175

do

ping -c 1 "$ip"

done
