I don't know if it's what you want, but if you're talking about the
output of a single command, then the following (or a variation) should
do. (using 'svn info' as the command).
---------------------------------------------------
import subprocess
from cStringIO import StringIO
import sys
buf = StringIO()
def popen(cmdline):
return subprocess.Popen(cmdline,
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT).stdout
for line in popen('svn info'):
print >> sys.stdout, 'out: ' + line,
print >> buf, 'buf: ' + line,
print
print buf.getvalue()
---------------------------------------------------
