Ping text file of ip addressese and output to text file

Shell Programming and Scripting
1

I am basically a scripting noob, I have some programming logic, and I wouldn't post here if my 3 hours of searching actually found something.

So far this is what I have:

"

#! /bin/ksh
List=./pinglist1.txt

cat $List | while read ip
do
Pingable=""
ping $ip -n 2 | awk '/100%/ {print "no"}' |read Pingable
if [[ "$Pingable" != "no" ]]
then
print $ip "PINGS">>pingresults.txt
else
print $ip "DOESN'T PING">>pingresults.txt
fi
done

"

pinglist1.txt is just a plain file with IP addresses.

I just want the script to ping each IP address and report if it is pinging or not to a text file.

Please and thanks.

Could you provide the output of your script?

Also, the 'dotslash' isn't necessary in

List=./pinglist1.txt

as './' tells the shell to use the $PWD.

Is the pinglist1.txt file in the same directory as the script?

I went ahead and got rid of the ./

and yes, the .txt is in the same directory

These are the results:

Well, I have minimal experience with shell scripting, but from the output, I see that it's erroring that your `ping' syntax is incorrect. Analyzing the script, you have the IP address of the host before `-n 2', which I believe to be incorrect.

Either way, I cannot help with `awk' syntax.

Looks more like ping syntax

Are you trying to do 2 echoes to ip, if so

ping -c 2 $ip | awk '/100%/ {print "no"}' |read Pingable

Thanks, now I can tell it is running the ping, and I went ahead and modified my code to this now:

#! /bin/ksh
List=pinglist1.txt

cat $List | while read ip
do
Pingable=""
ping -c 2 $ip | awk '/100%/ {print "no"}' |read Pingable
if [ "$Pingable" != "no" ]
then
print $ip "PINGS">>pingresults.txt
else
print $ip "DOESN'T PING">>pingresults.txt
fi
done

AND the results:
UX:sh (ping1.sh): ERROR: print: not found

Do I need to have a print.pl or something uploaded to that directory?

try echo...

 
  echo "$ip PINGS" >> pingresults.txt
else
  echo "$ip DOESN'T PING" >> pingresults.txt

Appreciate the responses, so far I am trying to read up on what to do next, the problems I am facing are I need to know how to step to the next line in the text file, and the results I got so far are troubling. I have 2 ip addresses so far in the text file, when the IP address that pings is first in the list, it prints:

--IP address 1-- PINGS

but when I have an IP address that doesnt ping first in the list it prints:

--IP address 2-- PINGS

I also modified my code to delete the results file at the start of the script

EDIT: I have removed the real IP addresses and just have them named --IP address 1-- and --IP address 2--

Give this a shot...

 
#!/bin/ksh
List=pinglist1.txt

cat $List | while read ip
do

  ping -c 2 $ip
  rc=$?
 
  if [[ "$rc" = "0" ]]
  then
    echo "$ip PINGS">>pingresults.txt
  else
    echo "$ip DOESN'T PING">>pingresults.txt
  fi
done

Thanks.

Ya, unfortunately I'm having the same problem, both programs just ping the first in the file and then quits.

I need to know how to step to the next line -a loop basically-(I am reading up on it as well)

Can you try this one:

#! /bin/ksh
IPLIST=`cat ./pinglist1.txt`
for ip in $IPLIST
do
echo $ip
ping -c 2 $ip >>log.txt
if [[ $? -eq 0 ]]
then
print $ip "PINGS">>pingresults.txt
else
print $ip "DOESN'T PING">>pingresults.txt
fi
done

THANKS.

I just had to modify it a bit, changed [] to and print to echo and it worked.

pingresults.txt produced the following (xxx for security purposes):

xxx.xxx.193.16 DOESN'T PING
xxx.xxx.135.194 PINGS

Thanks!
