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'%tmpdir
    errfn='%s/_err.msg'%tmpdir
    post="1>%s 2>%s"%(outfn,errfn)
    cmd2='%s %s'%(cmd,post)
    r=os.system(cmd2)
    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
