Wondering if anyone could shed some light on the subprocess module? I'll admit I'm not that great at the shell.
If I was wanting to get the size of the trash (on OS X), I could use: >>> os.system('du -sh ~/.Trash/') 11M /Users/jay/.Trash/ 0 Which gives me what I want. However, I've been reading that it's better to use subprocess. I did a test like so, but is this a good way to do this? >>> import subprocess >>> p = subprocess.Popen(['du', '-sh'], cwd='/Users/jay/.Trash/', >>> stdout=subprocess.PIPE) >>> out, err = p.communicate() >>> out ' 11M\t.\n' >>> err >>> And another question - why can't I use the tilde as a shortcut to the home directory? >>> p = subprocess.Popen(['du', '-sh'], cwd='~/.Trash/', >>> stdout=subprocess.PIPE) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 672, in __init__ errread, errwrite) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1202, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory: '~/.Trash/' Thanks for looking at my questions.
