How To Run Subscriber-Only Competitions on Your Blog

A Guest Post by David Cleland from TotalApps.

In 2006 I proudly started my first blog, DigMo! It was <a class="zem_slink freebase/guid/9202a8c04000641f800000000003ac3a" title="Technology" rel="wikinvest" href="http://www.wikinvest.com/industry/Technology">technology, it was creativity, it was music and it was <a class="zem_slink freebase/guid/9202a8c04000641f80000000000141ab" title="Education" rel="wikipedia" href="http://en.wikipedia.org/wiki/Education">education. Despite it being a bit of blog soup I was pleased at how quick the site grew but within a few years it reached a critical point beyond which I really couldn’t get the traffic to grow.

The best in command line xml: XMLStarlet

Thank fully someone pointed out XMLStarlet.? I now use XMLStarlet almost every day.? I work with a variety of REST based API&#8217;s gather information.

If you are on fedora then you can use xmlstarlet in the following way. First install the package:

Verify all the paths in the PATH directory

Here is the command to test that all the directories in your path actually exist.

(<a class="zem_slink freebase/en/internal_field_separator" title="Internal field separator" rel="wikipedia" href="http://en.wikipedia.org/wiki/Internal_field_separator">IFS=:;for p in $PATH; do test -d $p || echo $p; done)

and test all the directories with &#8221;test -d&#8221;

Here is another version without IFS:

for i in ${PATH//:/ };do test  -d $i || echo $i;done
