Shell Programming and Scripting

Yes, you must find a way to pass the host input into an array, like

Code:

awk -v hosts=host1,host2 'BEGIN {split (hosts,H,",")}'

Then you can cycle through them, as demonstrated here

Code:

for (i in H) print H[i]

The hosts= needs to be passed with -v at the beginning (not at the end as I did with the host=) so it is available in the BEGIN section.
Then in the existing code, where there is a reference to host replace it by a for loop through H.
I leave the actual implementation to you.
For clarity you can always use an explicit { block }, for instance

Code:

  for (i in H) { print H[i] }

or

Code:

  for (i in H) {
     print H[i]
   }
