Proposal: sh("<cmd> ...") as alias for sh.bash("-c", "<cmd> ...")

[axsaucedo]

Using sh extensively I often find myself having to use the sh.bash("-c", "<cmd> ..."). Although the sh.<cmd> interface is great initially for convenience, I often find myself adding the full command directly, whether for easier consistency when testing or due to limitations such as commands that contain a special character (-, ., etc). Indeed it's possible to bash = sh.bash.bake("-c") which is what I tend to do instead, but it would be quite convenient if this was supported by default as a contrib command that is accessible directly from the callable interface, and could potentially be a relatively simple interface (e.g. a __call__ implementation). Thanks for the great project!

Is the request something like this?

from sh.contrib import bash
bash.ls() # runs bash -c ls

[axsaucedo]

Thank you for your prompt reply! Yes exactly, the only extra I would add is being able to call directly - e.g:

from sh.contrib import bash
bash("command-with-dash [...]") # runs bash -c <cmd> [...] directly

Ok, I would merge it if you (or someone) made a PR. Here's the git contrib command to use as a template https://github.com/amoffat/sh/blob/develop/sh.py#L3467-L3471

Sounds good @amoffat - added #736 with functionality discussed:

Let me know if further changes requred - thanks!
