Thanks for your mail. What I mean is the workflow of software has changed totally. The meaning of upgrade is old features should work as it is and new features should be added. But in Fabric 2 my old fab file is not working. Below is my fab file example for your reference.
#from fabric.api import *
#env[root@host1, root@host2, root@host3:2022, root@host4, root@host5, root@host6]
# run('df -h')
I used to run this from my terminal like
$ fab ds > disk_space.txt
$ Enter your password :
Now this is not working. I checked some youtube videos about new fabric2 tutorials.
But i am not satisfied with the result fabric 1 was best.
Now i am using parallel-ssh
