Hello,
I want to call a system command (such as uname) that returns a string,
and then store that output in a string variable in my python program.
What is the recommended/most-concise way of doing this?
I could always create a temporary file, call the "subprocess.Popen"
module with the temporary file as the stdout argument, and then
re-open that temporary file and read in its contents. This seems
to be awfully long way of doing this, and I was wondering about
alternate ways of accomplishing this task.
In pseudocode, I would like to be able to do something like:
hostinfo = subprocess.Popen("uname -srvi") and have hostinfo
be a string containing the result of issuing the uname command.
Thanks for any tips,
Catherine
import os
txt = os.popen("uname -srvi")
hostinfo = txt.readline()
Or if the command outputs a number of lines (such as 'ls'),
use txt.readlines() to put the result into a list of strings.
