when take out cygwin , mingw out of path, error happens:

traceback (most recent call last):   file "<stdin>", line 1, in <module>   file "c:\python27\lib\subprocess.py", line 566, in check_output     process = popen(stdout=pipe, *popenargs, **kwargs)   file "c:\python27\lib\subprocess.py", line 710, in __init__     errread, errwrite)   file "c:\python27\lib\subprocess.py", line 958, in _execute_child     startupinfo) windowserror: [error 2] system cannot find file specified

is there way desired outcome without having store data in external file?

thanks in advance.

passing shell=true check_output seems work. suspect dir implemented shell (cmd) builtin rather independent executable.
