Let is start with this last piece: The reason why the system complains about not finding "ips.sh" is probably because it is not in the PATH: issue the following command:

Code:

echo $PATH

to see a list of directories separated by colons. Files in these directories you can call without using their full path (which is why you could use "cut" and "sort", etc.. They are all in "/usr/bin", which is in the PATH.), for all the others (this includes your current directory) you have to write:

Code:

cut -f 1 -d ' ' access.log | sort | uniq | /full/path/to/ips.sh

Another thing: sort | uniq is not necessary, because sort can do that too. Use the -u switch.

Code:

cut -f 1 -d ' ' access.log | sort -u | /full/path/to/ips.sh

This should work. I have no idea what dig does, but probably it displays something. You might want to quote "$junk" in the dig-line too. It will perhaps work anyway, but it is never too early to begin developing good habits and quoting variables to protect against them containing blanks is such a good habit.

For the same reason, you may want to define a variable before using it.

Code:

#!/bin/bash

typeset junk=""

while read junk 
do
         echo -n "$junk "         
         dig +short -x "$junk" 
done

I hope this helps.
