command piping like in plumbum

[rumly111]

Look at this code:

import sh
from sh import Command, ls, sed, sort

def command_or(self, other: Command) -> Command:
    return other.bake(_in=self(_piped=True, _return_cmd=True))

def command_getitem(self, args) -> Command:
    return self.bake(args)

Command.__or__ = command_or
Command.__getitem__ = command_getitem

if __name__=='__main__':
    pp = ls['-l', '-h', '-t'] | sed['1d'] | sort['-R']
    print(pp())
    jrnl = sh.journalctl | sh.tail['-n5']
    print(jrnl())

It introduces 2 small features. One is making Command.__getitem__ as a syntax sugar for .bake(), another is overriding Command.__or__ to make piping possible. As a result, we made it possible to have plumbum-style piping in sh!

Maybe it won't work in all cases, and I didn't think of every possible situation. But it's interesting proof of concept. If the project allows such "magic" in it, one or both features can be added.
