I can confirm the issue. An example:

cat /var/log/nginx/access.log | wc -l

3368

python -c "from envoy import run; print run('cat /var/log/nginx/access.log | wc -l').std_out"

47

Thanks @timgkeller – I should probably have presented a simpler test case. Maybe @kennethreitz could shine some light on this?

@bede I've also reported (+PR) this issue years ago, see #45, just read the "resolution" for it. I think this project is abandoned 😟 and so I've switched to sh (https://pypi.python.org/pypi/sh)

Ah, that's a pity. Cheers for the recommendation @chassing

I'm sorry to bother you again @chassing, but are you aware of any more Envoy-like solutions than Sh? Sh seems very powerful, but the syntax (at least as I understand it) becomes quite cumbersome for longer shell commands and with multiple pipes.

from envoy.

@bede You are right, the sh usage is a little bit different. Unfortunately I do not know any other envoy-like solutions, but if you found one, drop me a line.

@bede https://plumbum.readthedocs.org/ https://docs.python.org/3/library/pipes.html

@bede the problem is that envoy does not have "proper" piping support, see core.py where only around 10kB of data is passed to the next command. With that being said, you should try proclib for proper piping support.

Thanks @chassing @kernc @eugene-eeo : )
I hadn't come across plumbum or proclib, both of which look interesting. The streaming in Proclib is just what I'm after.

I think it's probably time this one was closed. Thanks again for the help.
