I've got a problem trying to build a easy backup/upgrade database script. The error is in the mysqldump call using subprocess: cmdL = ["mysqldump", "--user=" + db_user, "--password=" + db_pass, domaindb + "|", "gzip", ">", databases_path + "/" + domaindb + ".sql.gz"] print "%s: backup database %s \n\t[%s]" % (domain, domaindb, ' '.join...
Hi, I use a script that extends using the bash source feature; #!/bin/bash source someneatscriptthatendsprematurely.sh I would like to be able to return from that script, without breaking the main script. Using exit breaks the main script, return is only valid in functions and experimenting with $(exit 1) does not seem to work eith...
Hi guys, I have been searching for a way to start and terminate a long-running "batch jobs" in python. Right now I'm using "os.system()" to launch a long-running batch job inside each child process. As you might have guessed, "os.system()" spawns a new process inside that child process (grandchild process?), so I cannot kill the batch ...
My Django app stops working when deployed on Apache ( with mod_wsgi ). It runs on a Windows server. The app calls on a windows executable called "rex" ( Alchemy Remote Executor ) which executes a command on another remote windows box. process = subprocess.Popen( ['rex',ip,usr,pwd,command], stdout=subprocess.PIPE, universal_newlines=...

Hello, I'm running an SSH process like this: sshproc = subprocess.Popen([command], shell=True) exit = os.waitpid(sshproc.pid, 0)[1] This works and opens an interactive terminal. Based on the documentation for subprocess, sshproc is using the script's sys.stdin. The question is: how can I print to stderr or a file what input is bein...

I am looking for a way to decrypt pgp messages in python without the use of a subprocess. I have checked out http://wiki.python.org/moin/GnuPrivacyGuard but none of those solutions worked. Pyme almost worked except I hit a wall when trying to use set_passphrase_cb to avoid any user interaction but couldn't get it working ( http://stackov...

Hi All, probably a daft question but.... I'm running a script from crontab that will just ssh and run a command and store the results in a file. the function that seems to be failing is subprocess.popen Here is the function def _executeSSHCommand(sshcommand,user,node): ''' Simple function to execute an ssh command on a remo...
I'm using python to manage some simulations. I build the parameters and run the program using: pipe = open('/dev/null', 'w') pid = subprocess.Popen(shlex.split(command), stdout=pipe, stderr=pipe) My code handles different signal. Ctrl+C will stop the simulation, ask if I want to save, and exit gracefully. I have other signal handlers ...
I have following script: #!/usr/bin/python while True: x = raw_input() print x[::-1] I am calling it from ipython: In [5]: p = Popen('./script.py', stdin=PIPE) In [6]: p.stdin.write('abc\n') cba and it works fine. However, when I do this: In [7]: p = Popen('./script.py', stdin=PIPE, stdout=PIPE) In [8]: p.stdin.write('...
Hello, all, I want to create a GUI python script to launch several processes. All of these processes originally were called by setting up a shell with a perl script (start_workspace.perl), and type the executable file name under the shell. inside, start_workspace.perl, it first set some ENV variables, and then call exec(/bin/bash), wh...
I'm working on a toy language, and I've implemented the ability to stream lines of text from shell commands lazily (as a generator). Currently, my code to do this looks like: #!/usr/bin/env python3 import signal,subprocess,select # suppress 'broken pipe' error messages signal.signal(signal.SIGPIPE, signal.SIG_DFL) def shell_exec(cmd)...
I hava a Java process that spawns a new JVM using ProcessBuilder etc. While debugging this, is it possible to have Eclipse attach a debugger to the new sub-process? Even better, is there any plugin that will do this automatically when it notices the new child process? I'm told (though haven't seen) that VisualAge used to be able to do t...
Hi all, I'm developing an application in Python on Ubuntu and I'm running external binaries from within python using subprocess. Since these binaries are generated at run time and can go rogue, I need to keep a strict tab on the amount of memory footprint and runtime of these binaries. Is there someway I can limit or monitor the memory u...
I'm trying to follow the info I can find about subprocess.Popen as I want to make a linux command line call.. I am trying as below but am getting the error "[Errno 2] No such file or directory". I'm not trying to open a file so I don't understand this error, and it works fine (although with other issues relating to waiting for the proce...
I am having an issue when making a shell call from within a multiprocessing.Process(). The error seems to be coming from Git, but I just can't figure out why it only happens from within a multiprocessing.Process(). Note, below is an example to demonstrate what's happening... in real code there is a lot more going on within the Process(...
