get ip address from a file and output result in a table - bash

Question

Im trying to get all ip address from file called ipserver.txt and check if the ip address is down or up.
In the file ipserver.txt I have ip address that looks like this:
# My text file ipserver.txt
host1 10.0.0.1
host2 192.168.10.23
host3 192.168.0.1
host4 192.168.23.10
# My script
date
cat ipserver.txt | while read output
do
ping -c 1 "$output" > /dev/null
if [ $? -eq 0 ]
then
# echo -e "\n\033[4;31mHOSTNAME\033[0m \t\t\033[1;4;31mIP\033[0m"
echo "$output is up"
# printf $output >> resultat
else
echo "$output is down"
fi
done
# cat resultat
What Im trying to output is a table of all ouputs like this:
HOSTNAME IP UP/DOWN
--------------------------------------------
host1 10.0.0.1 UP
host2 192.168.10.23 DOWN
host3 192.168.0.1 UP
host4 192.168.23.10 DOWN
--------------------------------------------
In my script Im trying to redirect the $output to resultat, but dont now if Im thinking right.
In text file ipserver.txt I can check the ip address from the file if I dont write host1, host2, host3 and host4.
Can somebody give me a tip on how to resolve my script, so I can get the output that i want

Answer 1

This will do what you want:
#!/bin/bash
printf "HOSTNAME\tIP\t\t\tUP/DOWN\n"
echo "----------------------------------------------------------"
while read -r host ip
do ping -c 1 "$ip" > /dev/null 2>&1 && printf "$host\t\t$ip\t\tUP\n" || printf "$host\t\t$ip\t\tDOWN\n"
done < ipserver.txt
echo "----------------------------------------------------------"
Probably best to put that in a script. If you want to send the results to a file, redirect the entire output. i.e. if you called it test-servers and made it executable:
./test-servers >> resultat

I think you're looking for printf, does the following work for you?
date
i=1
cat ipserver.txt | while read output
do
extr=${output#"host$i"}
ping -c 1 "$extr" > /dev/null
if [ $? -eq 0 ]
then
printf "%-16s %-16s %s\n" "host$i" $extr "UP"
else
printf "%-16s %-16s %s\n" "host$i" $extr "DOWN"
fi
((i++))
done
