Please don't use "sh" python library!

By default (1) captures stdout and stderr of all processes and (2) create tty for processs stdout.

Those are really bad defaults. The tty on stdout means many programs run in "interactive" rather then "batch" mode: programs which use pager get output truncated, auto-colors may get enabled and emit ESC controls into output streams (or not, depending on user's distro... fun!). And captured stderr means warnings and progress messages just disappear.

For example, this hangs forever without any output, at least if executed from interactive terminal:

    from sh import man
    print(man("tty"))

Compare to "subprocess" which does the right thing and returns manpage as a string:

    import subprocess
    subprocess.check_output(["man", "tty"], text=True)
   

Can you fix "sh"? sure, you need to bake in option to disable tty. But you've got to do it in _every_ script, or you'll see failure sooner or later. So it's much easier, not to mention safer, to simply use "subprocess". And as a bonus, one less dependency!

(Fun fact: back when "sh" first appeared, everyone was using "git log" as an example of why tty was bad (it was silently truncating data). They fixed it.. by disabling tty only for "git" command. So my example uses "man" :) )
