that was good, but on python2.4

subprocess is GREAT! e.g.:

pipe = subprocess.Popen(tot, stdout=subprocess.PIPE,\
stderr=subprocess.PIPE, shell=False)
message = pipe.stdout.read()
error = pipe.stderr.read()

thanks all,

footnote: subprocess is available for Python 2.2 and later, from

I see. I saw also os.popen("").read() or so.

Anyway, not sure if that would also catch stderr?

But doesn't matter. It seems, imagemagick (binaries) won't provide
proper error-codes, but at least when it prints something, something was
not ok probably. 

I will check the resulting file, to see if everything went ok, and try
to catch the output like you mentioned.

thanks a lot

If I understand you correctly, this presentation depends on
  executable.exe
not emitting any blank lines.  Some legitimate command-line
executables *do* have occasion to put out blank lines, though 
...

You should give a go to os.popen(  ). Article
6.1.2 and 6.1.3 in the Python Library doc.

I recently wrote a program that would create a pipe using the popen()
method, and would enter a while loop. At each iteration, it would read
one line of the pipe output, and the loop would break when it gets an
empty line (indicating the running application is not running in this
case).

Example:

import os

oPipe = os.popen( "run C:/program files/my app/executable.exe" )

while 1:
sLine = oPipe.read()
print sLine
if sLine == '':
print 'No more line from pipe, exit.'
break



Cheers

get output of cmd-line command under MS windows

[calmar]

Hi all,

unfotunately, 'commands.getstatusoutput(command)' does not work under
windows.

Would there be any alternative?

os.system also just provides the exit number I think.

thanks a lot, 
and cheers
