Hi,
I need to do the following thing.
On the first host, calculate the checksum of a certain file (es.
/etc/hosts) and save it into a variable, let's say "file_checksum".
On the second host, I would like to calculate newly the checksum and
compare it with the one from the first host (i.e. the value saved in
"file_checksum"). And so on with the other hosts of my inventory.
I tried several ways without success. Also run_once on set_fact doesn't
seem to work (see below the snippet not fully working).
Any Idea how to save a value between hosts in a playbook?
Thanks in advance.
Cheers.
Gaetano
