Hi,
Do we have any facility to append file from Popen()/call(); see below
example...
1 import subprocess
2 f=open('log', 'w')
3 ...# writing some log-into into log file
4 p = subprocess.Popen(cmd, stdout=f, stderr=f) # (Q)
5 ...# do remaining stuff
Q: At line# 4, the output of the 'cmd' will wipe-out everything in
'log' file. So to avoid this do we have any mechanism to append into
the existing file from subprocess.
Currently I am doing following...
p = subprocess.Popen(cmd, stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
o, e = p.communicate()
print >> log, o
print >> log, e
Pleaese let me know if there is any better mechanism.
Thank you in advance.
