Windows version of Python 2.6.4: Is there any way to determine if subprocess.Popen() fails when using shell=True?
Popen() successfully fails when shell=False >>> import subprocess >>> p = subprocess.Popen( 'Nonsense.application', shell=False ) Traceback (most recent call last): File "<pyshell#258>", line 1, in <module> p = subprocess.Popen( 'Nonsense.application' ) File "C:\Python26\lib\subprocess.py", line 621, in __init__ errread, errwrite) File "C:\Python26\lib\subprocess.py", line 830, in _execute_child startupinfo) WindowsError: [Error 2] The system cannot find the file specified But when shell=True, there appears to be no way to determine if a Popen() call was successful or not. >>> p = subprocess.Popen( 'Nonsense.application', shell=True ) >>> p <subprocess.Popen object at 0x0275FF90> >>> p.pid 6620 >>> p.returncode >>> Regards, Malcolm -- http://mail.python.org/mailman/listinfo/python-list
