Shell Programming and Scripting

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

Code:

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...

Code:

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