The Following can be used to find the first RAR file in a multi-volume archive. It will find *.part01.rar or *.rar depending on the naming convention in use.
.*[^p][^a][^r][^t]..\.rar$|.*part01\.rar$
If you need to find all the RAR files and SFV files (probably to delete them after extraction), the following will get them all.
.*\.r[0-9]{2}$|.*\.rar$|.*\.sfv$
#!/bin/bash
find . -name '*.py' | xargs cat | sed '/^\s*#/d;/^\s*$/d' | wc -l
xargs converts find’s output to arguments, the sed RE drops comments and blank lines, and wc counts them lines. Thanks to these posts on stack overflow for some reference material.
If you want to match a slug in your urls.py, use (?P[-\w]+) as a named match pattern:
So, if you wanted to match http://example.com/some-slug-name/, you would use
urlpatterns = patterns('',
# ...
url(r'^(?P<slug>[-\w]+)/$', some_view),
# ...
