Storing Subprocess Results

[topazcode]

I am using the subprocess module to run some shell commands on a Linux
system:

import subprocess
output = subprocess.call ('''ssh server1 "uptime"''' , shell=True)

The above assigns the output variable with a return code, i.e. 0 in
this case. How can I actually capture the data returned from
subprocess.call , rather than just the return code? I'd like to have
the output variable contain the uptime string in this case. Any help
is appreciated. Thanks.

Use subprocess.Pope n instead of call.

The above assigns the output variable with a return code, i.e. 0 in

Probably commands module is a better choice for your problem:

>>import commands
>>commands.geto utput('fortune' )

Thanks guys. I went ahead and used subprocess.Pope n as suggested and
that works fine. Did something like:

import subprocess
subprocess.Pope n("uptime", shell=True, stdout=subproce ss.PIPE,
stderr=subproce ss.PIPE)
stdout_value, stderr_value = subprocess.comm unicate()

The above worked great. The 'uptime' was actually a fairly long
stretch of commands, and this allows me to check for STDERR and act
accordingly. Thanks again for the help and suggestions.
