Remove some path from the PATH variable temporarily.

How many times has it happened to you that you are working on some linux platform (like Fedora/Ubuntu/CentOS etc) and suddenly you see that you need to remove some path from the PATH variable so that a script is executed from some other path. It really difficult to do this if the path is too long and if you end up doing this couple of times. If that is the case, then the below script is for you 🙂

Speed up mkat with no md5sum for the files.

mkat details:

mkat is a set of <a class="zem_slink" title="Command-line interface" rel="wikipedia" href="http://en.wikipedia.org/wiki/Command-line_interface">command line tools to burn, catalog <a class="zem_slink" title="Data" rel="wikipedia" href="http://en.wikipedia.org/wiki/Data">data CD/<a class="zem_slink" title="DVD" rel="wikipedia" href="http://en.wikipedia.org/wiki/DVD">DVD, <a class="zem_slink" title="Compact Disc" rel="wikipedia" href="http://en.wikipedia.org/wiki/Compact_Disc">audio CDs and then search the catalog <a class="zem_slink" title="Database" rel="wikipedia" href="http://en.wikipedia.org/wiki/Database">database, e.g. check whether you have a certain file or audio CD in your collection. Tags can be used to categorize CDs, e.g. <a class="zem_slink" title="Comedy" rel="wikipedia" href="http://en.wikipedia.org/wiki/Comedy">comedy, <a class="zem_slink" title="Drama" rel="wikipedia" href="http://en.wikipedia.org/wiki/Drama">drama, etc. Audio CD support is very rudimentary though.

My comment : fc is the fix command of the bash builtin.
This is similar to using `!!` or

Using SQLite to maintain your monthly bills.

I was looking for a small application to maintain my every month bills. The application had to be small and script-able. I basically wanted to keep track of the bills that have been generated and pending payment and the bills that have been paid.

First we will create the <a class="zem_slink" title="Database" rel="wikipedia" href="http://en.wikipedia.org/wiki/Database">database schema with the following command:

  <td>
    <div class="text codecolorer">
      CREATE TABLE bills(name varchar(20), due_dt text, p_dt text, amount integer);
    </div>
  </td>
</tr>

So, I built on the knowledge gathered on <a class="zem_slink" title="SQLite" rel="homepage" href="http://sqlite.org/">SQLite. And here is a small script that I wrote:

SQLite – simple use in scripts

Today we will look a the most simple use&#8217;s in the scripts and how to use them.

echo &#8221;insert into bills values (&#8221;$name&#8221;,$date_now, $date_now,$1)&#8221;|sqlite bills

or the other way to do this is

<a class="zem_slink" title="SQLite" rel="homepage" href="http://sqlite.org/">sqlite3 bills &#8221;insert into bills values (&#8221;$name&#8221;,$date_now, $date_now,$1)&#8221;

OK, now in the next post we will see a simple application that I am currently developing or planning.<h6 class="zemanta-related-title" style="font-size: 1em;">Related articles by Zemanta <ul class="zemanta-article-ul"> <li class="zemanta-article-ul-li"><a href="http://tobu.lightbird.net/">Tobu Tutorial (tobu.lightbird.net) <li class="zemanta-article-ul-li"><a href="http://go.theregister.com/feed/www.theregister.co.uk/2010/07/02/openoffice_adopts_gstreamer/">OpenOffice gets Ubuntu-media friendly (go.theregister.com) <li class="zemanta-article-ul-li"><a href="http://elegantcode.com/2010/07/02/using-transactionscope-with-sqlite/">Using TransactionScope with SQLite (elegantcode.com) <li class="zemanta-article-ul-li"><a href="http://www.slideshare.net/aikisteve/flash-and-the-city-2010">Flash And The City 2010 (slideshare.net) <div class="zemanta-pixie" style="margin-top: 10px; height: 15px;"><a class="zemanta-pixie-a" title="Enhanced by Zemanta" href="http://www.zemanta.com/"><img class="zemanta-pixie-img" style="border: medium none; float: right;" src="http://img.zemanta.com/zemified_e.png?x-id=7b7c893c-d92b-44bc-8923-d7c6fddc8b42" alt="Enhanced by Zemanta" /><span class="zem-script more-related pretty-attribution">
