UNIX for Dummies Questions & Answers

I'm using a hosts file, formatted like this:

xxx.xxx.xxx.xxx dnsname #comment

Current command is:

for host in 'awk '/^[0-9]/ { print $1 }' etc/hosts'
do
ping $host 1 2>&1 | \
sed 's/.*no answer.*/[31;1m&[0m/;s/.*is alive.*/[32;2m[0m/'
done

(no answer returns red, is alive green)

How can I ping the IP, and have it return xxx.xxx.xxx.xxx is alive, along with the dnsname AND comment?

"xxx.xxx.xxx.xxx is alive dnsname #comment" for the output when just pinging the IP? Is this possible?

Using Solaris 5.5. Not a big Unix geek by any measure. Just trying to enhance a ping script a bit.

Thanks in advance...

Code:

#!/bin/ksh

hosts='/etc/hosts'

while read ip host theRest
do
   ping "${ip}" 1>/dev/null 2>&1
   [[ "${?}" -eq 0 ]] && echo "${ip} is alive ${host} ${theRest}"
done < "${hosts}"

Vgersh99,

Thanks for replying. I've put in your snippet, and it works as long as the IP ping is "alive". For a bad ping, there's no output on the screen. Is there a way to add that? Our main goal is to quickly identify a bad ping, which with the prior code came out red.

Also, I added in the color snippet after ${theRest}" using a |. Now the entire printout is green. I'd assume that a bad one would be all red?

Thanks again!

Code:

#!/bin/ksh

hosts='/etc/hosts'

while read ip host theRest
do
   ping "${ip}" 1>/dev/null 2>&1
   [[ "${?}" -eq 0 ]] && echo "${ip} is alive ${host} ${theRest}" || echo "${ip} is dead ${host} ${theRest}"
done < "${hosts}"

I added the color snippet, but only the red works on the failed pings (no green for the good pings). Is there a way to make the good pings green and the bad ones red? Have played around with the code and only get one color to show, either on the bad or good pings, but not both. Seems that the last argument is the only one to read the color code?

#!/bin/ksh

hosts='/etc/hosts'

while read ip host theRest
do
ping "${ip}" 1>/dev/null 2>&1
[[ "${?}" -eq 0 ]] && echo "${ip} is alive ${host} ${theRest}" || echo "${ip} IS DEAD!!! ${host} ${theRest}"
sed 's/.*IS DEAD!!!.*/[31;2m[0m/;s/.*is alive.*/[32;1m&[0m/'


done < "${hosts}"

Again, TIA.

Never mind...figured it out. Just entered the color code before the double pipe and at the end of the second argument.


Thanks again!!
