# ansible-console is an interactive REPL shell for ansible
|
|
# with built-in tab completion for all the documented modules
|
|
#
|
|
# Available commands:
|
|
# cd - change host/group (you can use host patterns eg.: app*.dc*:!app01*)
|
|
# list - list available hosts in the current path
|
|
# forks - change fork
|
|
# become - become
|
|
# ! - forces shell module instead of the ansible module (!yum update -y)
