Jovik added the comment: I'm quite aware of the os.sep issues between the systems, but I checked both out of curiosity. Here are latest results:
All of the following commands raises the same exception: >>> proc = subprocess.Popen("plink", stdout=subprocess.PIPE, >>> cwd="c:\\python33\\workspace") >>> proc = subprocess.Popen("plink", stdout=subprocess.PIPE, >>> cwd="c:\\python33\\workspace\\") >>> proc = subprocess.Popen(".\plink", stdout=subprocess.PIPE, >>> cwd="c:\python33\workspace") >>> proc = subprocess.Popen(".\\plink", stdout=subprocess.PIPE, >>> cwd="c:\\python33\\workspace") >>> proc = subprocess.Popen("plink", stdout=subprocess.PIPE, >>> cwd="c:/python33/workspace") Traceback (most recent call last): File "C:\Python33\lib\subprocess.py", line 1104, in _execute_child startupinfo) FileNotFoundError: [WinError 2] The system cannot find the file specified During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Python33\lib\subprocess.py", line 819, in __init__ restore_signals, start_new_session) File "C:\Python33\lib\subprocess.py", line 1110, in _execute_child raise WindowsError(*e.args) FileNotFoundError: [WinError 2] The system cannot find the file specified But, when I set shell=True, then everything works just fine: >>> proc = subprocess.Popen("plink", stdout=subprocess.PIPE, >>> cwd="c:\python33\workspace", shell=True) >>> proc = subprocess.Popen(".\plink", stdout=subprocess.PIPE, >>> cwd="c:\\python33\\workspace", shell=True) >>> proc = subprocess.Popen(".\\plink", stdout=subprocess.PIPE, >>> cwd="c:\\python33\\workspace", shell=True) >>> proc = subprocess.Popen("plink", stdout=subprocess.PIPE, >>> cwd="c:/python33/workspace", shell=True) I can get plink's output afterwards with proc.communicate() ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20927> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
