Ansible ad-hoc command syntax

[Trevor]

Hello all,

Got a question regarding the following 3 ad-hoc syntax:

1)   ansible  hostname   -m  command  -a  uptime

2)   ansible  hostname   -m  shell  -a uptime

3)   ansible  hostname   -a  uptime

Okay, I get the same outupt - same results from running either command.  My question
is, other than saving some keystrokes with the 3rd format, is there any other benefit to
using this (3rd item) syntax vs. the first two?

Thanks all.

Hello, @Trevor 

There is no difference between ansible hostname -m command -a uptime and ansible hostname -a uptime. The command module is used by default for the -m option. But the big difference between them both and ansible hostname -m shell -a uptime The shell is not used to execute the command for the command module, but the shell is run for the shell module. Compare: ansible hostname -a set and ansible hostname -m shell -a set
