Python batching on XP

[durumdara@mailpont.hu]

Hi !

I want to write a program that backup some databases in the night.

Pseudo like this:

try:
if cmd('net stop dbservice'):
s=c://backup'+str(tim e.time())+'.zip '
if cmd('zipit c:\\database '+s):
if cmd('map drive \\\\backupdrive \\c$ y -user BACKUP -pwd SECRET'):
if cmd('copy '+s+' y:\\'):
LogSucc()
finally:
cmd('net start dbservice')

I'm trying with os.system() commands.
But that is printing the result message to the screen, not to a tuple,
like commands.|getst atusoutput().
I need to store this message, because I want to log everything that this
program do/print; every of the messages.

So: how to I capture the screen, or how to I use
|commands.|gets tatusoutput() to access the Windows batch/cmd commands,
and get their errors/statuses ?

Please help me !

Thanks for it: dd

You should take a look at the subprocess module

Hi !

I have Py 2.3.5, and subprocess is placed in version 2.4.

The os.popen is not good, because it is not get return value. I can read
the return value, but the message is os dependent (XP, 2k, NT).
I create this function. It is not too good, but it is working:

def Cmd(cmd,tmpdir= "./"):
outfn='%s/_out.msg'%tmpdi r
errfn='%s/_err.msg'%tmpdi r
post="1>%s 2>%s"%(outfn,er rfn)
cmd2='%s %s'%(cmd,post)
r=os.system(cmd 2)
f=open(outfn,"r ")
try:
s1=f.read()
finally:
f.close()
f=open(errfn,"r ")
try:
s2=f.read()
finally:
f.close()
s="\n".join([s1,s2]).strip()
return (r,s)

Anyone have a better idea ?

Thanks for it: dd
