How can I get terminal output in python
>>> import subprocess
>>> cmd = [ 'echo', 'arg1', 'arg2' ]
>>> output = subprocess.Popen( cmd, stdout=subprocess.PIPE ).communicate()[0]
>>> print output
arg1 arg2
>>>
There is a bug in using of the subprocess.PIPE. For the huge output use this:
import subprocess
import tempfile
with tempfile.TemporaryFile() as tempf:
proc = subprocess.Popen(['echo', 'a', 'b'], stdout=tempf)
proc.wait()
tempf.seek(0)
print tempf.read()
Are there any code examples left?
