Re: commands.getstatusoutput result is not command line exit value!!!

ok, I was thinking of shifting using subprocess, guess I'd better do that and forget about this waste of time. thanks Hari Sekhon Fredrik Lundh wrote: Hari Sekhon wrote: I'm sorry, this may seem dense to you but I have to ask. What on earth are you talking about? > Why is it shifted 8 bits to the left? Why is there bitshifting at all? Why doesn't commands give the same exit value as os.system() and the unix cli? because that's how Unix's wait() operation returns the status code (as mentioned in the "commands" section of the library reference). you can use the os.WIFEXITED(status) and os.WEXITSTATUS(code) helpers to convert between wait return codes and signal numbers/exit codes. see: http://docs.python.org/lib/os-process.html or you can forget about the obsolete "commands" module, and use the new subprocess module instead; e.g. def getstatusoutput(command): from subprocess import Popen, PIPE, STDOUT p = Popen(command, stdout=PIPE, stderr=STDOUT, shell=True) s = p.stdout.read() return p.wait(), s print getstatusoutput("ls -l /bin/ls") (0, '-rwxr-xr-x 1 root root 68660 Aug 12 2003 /bin/ls\n') the subprocess module is highly flexible; see the library reference for details. </F>
