pexpect

This is related to my another post multithreading issue with wx.TextCtrl (or underlying GTK+) , which after correction with calling GUI interactions from primary thread, I find it again comes to the pipe block buffering problem. so How to get spontaneous output from the subprocess.stdout? To be in short, currently I am using subprocess.popen to launch an external long-time running program. launchcmd=["EXTERNAL_PROGRAM_EXE"] p = subprocess.Popen(launchcmd, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE) self.outputThread = BashProcessThread(p.stdout.readline) self

I need to call a shellscript from python. The problem is that the shellscript will ask a couple of questions along the way until it is finished. I can't find a way to do so using subprocess ! (using pexpect seems a bit over-kill since I only need to start it and send a couple of YES to it) PLEASE don't suggest ways that requires modification to the shell-script! Using the subprocess library, you can tell the Popen class that you want to manage the standard input of the process like this: import subprocess shellscript = subprocess.Popen(["shellscript.sh"], stdin=subprocess.PIPE) Now shellscript

I've stumbled upon pexpect and my impression is that it looks roughly similar to fabric . I've tried to find some comparison, without success, so I'm asking here--in case someone has experience with both tools. Is my impression (that they are roughly equivalent) correct, or it's just how it looks on the surface ? Jon I've used both. Fabric is more high level than pexpect, and IMHO a lot better. It depends what you're using it for, but if your use is deployment and configuration of software then Fabric is the right way to go. Jasper van den Bosch You can also combine them, to have the best of

These patterns

How to login the super user(root) in remote host system using pexpect? user = root user password = 'pass' child = pexpect.spawn('ssh %s@%s'%(user,host,)) You could also simply log in to a user on ssh like normal, then send commands to log into the root like you normally would in a terminal. #log into user account child = pexpect.spawn('ssh clientuser@localhost') child.expect('Password:') child.sendline('password') #then log into root account child.sendline('su') child.expect('Password:') child.sendline('sudopassword1234') This is just longer and more code, and probably only works on linux the
