How to write an ansible task to check if the physical memory \>=128 MB and free disk is \>= 256 MB. i tried to get the output but i am not sure how to proceed further.

```auto
# Check the physical disk memory 128 MB and free disk 256 MB
 - name: check the physical memory
   command: free -m
   register: phy_mem

```

I'd use facts for that. The ones you want are probably

ansible\_memtotal\_mb

(total RAM in Mb)

and

ansible\_mounts

(which gives free bytes per mounted device)
