Recurse Directories and process files in directory

[Jason Nordwick]

Use os.system to execute a string and os.walk to get a recursive list of files


>>> def processdir(curdir,subdirs,files):
...     map(lambda f:os.system('\\cygwin\\bin\\wc -l "%s"' % f), [curdir+os.sep+x for x in files])
...
>>> map(lambda x:processdir(*x), os.walk('\\dev\qclient'));
