Easier Reinstalls

I typically reinstall my computer operating system every six months. The reasons for this are that it cleans out the system and reinstalls require me to be in front of the computer for a total of about ten minutes so it&#8217;s painless. Notice I said &#8221;in front of the computer&#8221;, the system does all of the work for me with some specially crafted bash scripts.

coproc help - a new feature in bash

In the <a class="zem_slink freebase/en/bash" title="Bash" rel="homepage" href="http://tiswww.case.edu/php/chet/bash/bashtop.html">bash version 4.0, there is a new concept called coproc. This is very useful for some of the daily tasks.

Transfer all the google feed URLs to rss2email.

Next step in restoring my settings was to get the working rules and all the blogs into rss2email. I have subscribed to more than 150 blogs. So, adding all of them manually was difficult.

For a time like this, I subscribe to all the blogs using google reader and then add them to rss2email. So I had quickly exported the google feeds list and then had to find a way to extract the URLs for the blog to the rss2email. The command to add a url is r2e add, so I wrote this one line just now to do the task for me.

top - looks better and is more useful with a rc file...

top is a very useful command to find out who is eating up the <a class="zem_slink freebase/en/central_processing_unit" title="Central processing unit" rel="wikipedia" href="http://en.wikipedia.org/wiki/Central_processing_unit">CPU or the memory. But sometimes the plain and simple look simply would be boring so how about some fun. Copy the below code to file : ~/.toprc
