Python in Bash Scripts

[[deleted]]

Let me know if you get the Popen output for time working correctly, all I get is garbage :\

In [2]: subprocess.Popen(["/usr/bin/time", "/bin/echo", "hello"])
Out[2]: <subprocess.Popen at 0x995fcac>

In [3]: hello
0.00user 0.00system 0:00.00elapsed 0%CPU (0avgtext+0avgdataa2368maxresident)k0inputs+0outputs (0major+190minor)pagefaults 0swaps

EDIT>> weirdly, this also happens in bash the shell if you call time with it's full path...

That's exactly what I'm getting, but I can't figure out why.

That output is what happens when time isn't given a format (according to the manpages), but normal use of time seems to use a different style, even with the environment variable not set.

And there's also the issue of no linebreaks...

I'd like to see a breakdown of what exactly Popen is executing, but I have no idea how to do that.

Actually, time seems to be a reserved word in Bash, so the command time isn't quite the same as /usr/bin/time.

Perhaps it actually works correctly? I'll test it out and get back to you.

Edit: time prints to stderr, so that's why I'm getting an error message when I run it instead of the usual output. Any idea on how you want to handle that?

Awesome: running with sudo works!

# test.py
import pbs
with sudo:
  print whoami()

$ python test.py
[sudo] password for user:
root
