Compare files on two different remote hosts

[jaso...@tappcg.com]

Does anyone know of a way to compare a file that resides on two separate hosts before and/or after a deployment? Meaning, I want to compare foo.conf on host1 against foo.conf on host2. If there are disparities, then list them in an output file. 

I've read about a number of ways to potentially approach this (using diff command, shell module, stat module with get_checksum param, check mode, etc.). But none of them have given exactly what I need yet.

Thanks for any advice.

Use the fetch module to get the file to the Ansible controller, then you can diff them.

If diff is not what you need I'm out of ideas since diff print out the differences in two text files.
