[Python]How to convert/record the output of subprocess into file

[ljjfb]

Hi all professionals,

I uesd subprocess module to spawn a new process and then implement the command. The final result is the output via stdout.
Here is the code I wrote:

import subprocess
proc = subprocess.Popen('egrep \'^HTTP/\' *', shell=True, stdout=subprocess.PIPE,)
stdout_value = proc.communicate()[0]
print 'results:'
print stdout_value

And the results are:
063.245.209.093.00080-128.192.076.180.01039:HTTP/1.1 302 Found
063.245.209.093.00080-128.192.076.180.01040:HTTP/1.1 302 Found

My question is: How to convert/record these results into a file?

I appreciate all your responses and helps!

You can write

with open("output.txt", "w") as fileout:
    fileout.write(stdout_value)

Gribouillis updated

Information like this will always need a callback into action. Therefore i thought of updating your script a little.

with open("logfile.txt","a+") as logfile:
     logfile.writelines(str(stdout_value)+"\n") # To get the newline. easy to work with that

In the end. You can read-in your data for further manipulation if needed.
I understand Gribouillis just gave you a simple pseudo just to give you the idea.
