OSExtension 0.1.5

Testing if a path is a file (shortcut for try/with open):

fs.isfile('something')
fs.isfile('something', mode='r')

Shortcut for rsync -a

Uses `sh module <https://pypi.python.org/pypi/sh/>`__.

fs.sync('name@somehost:~/somedir/', 'local_path')
fs.sync('~/somedir', '.')

Returns exit code and does not catch any exceptions raised by sh.

Check if a file is the same based on modified time

Example use: determine if a file is the same based on a HEAD HTTP request using the Last-Modified header.

from urllib2.request import urlopen

req = urlopen('http://i.imgur.com/sgon5YP.jpg')
req.get_method = lambda: 'HEAD'
last_modified = None

for line in str(req.info()).split('\n'):
    if 'last-modified' in line.lower():
        last_modified = line.split(': ')[1].strip()
        last_modified = time.strptime(last_modified.replace(' GMT', ''), '%a, %d %b %Y %H:%M:%S')
        break

# Actual check
fs.has_same_time('./sgon5YP.jpg', last_modified)

Delete a set of files

Use fs.rm_files(list_of_files, raise_on_error=bool_val).
