Hi there,

I am new to Ansible and I am learning this toolkit. When I am dealing w/ the output, I find there are various ways to handle the variables. Some examples shows “debug = xxx.stdout”, Some examples mention “xxx.stdout\_lines” and “xxx.stdout\_lines[0]”. Is there anyone can share more info definition of these outputs and any whitepaper / tutorials to describe the details?

Thanks  
Leon Lai
