How about inserting a print cmd before the line child = Popen(cmd) ? Depending on its value it may not even be a missing command, e. g. This doesn't work: Python 2.6.7 (r267:88850, Sep 28 2012, 16:26:39) [GCC 4.6.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import subprocess >>> subprocess.Popen("ls -1") Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.6/subprocess.py", line 623, in __init__ errread, errwrite) File "/usr/lib/python2.6/subprocess.py", line 1141, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory But this works: >>> subprocess.Popen(["ls", "-1"]) <subprocess.Popen object at 0x7f8b31c5cfd0> >>> alpha beta gamma And this works, too (but is a bit less robust): subprocess.Popen("ls -1", shell=True) <subprocess.Popen object at 0x7f8b31c5cd90> >>> alpha beta gamma -- https://mail.python.org/mailman/listinfo/python-list
