Improved ways to get raw output from the shell.

Is your feature request related to a problem? Please describe

So I’m often needing ways to branch python code based on actual raw output from a shell command (Use case: in-depth system audits).

host.fact.command() does this fairly well, but it lacks any ability to switch users or permissions on the fly. Operations have plenty of ways to do this using parameters such as sudo= use_sudo_password= su_user=… etc.

Describe the solution you’d like

One or more of the following would be ideal.

• Give host.fact.command() some form of equivalent to the user switching parameters enjoyed by Operations.
• Allow us to get raw output from the server.shell() Operation.

Update on this: have implemented the change in https://github.com/Fizzadar/pyinfra/pull/516/commits/bc9d1182c8a76eb4171c4fb1ba5509e2ed2d1b66; need to add some tests and then should be good to go for 1.4 release shortly!

I think this is an absolute must-have; I’m going to implement this alongside the new explicit fact imports functionality, so can do:

host.get_fact(AptSources, sudo=True)

Will have the neat side effect of allowing operations to customise fact global arguments they use (by default facts called by an operation inherit the operation args).
