Change the firefox theme without restarting.

How often you wished that you could change the theme for firefox without restarting. Well sometime back Mozilla came up with Light weight themes called personna’s but if that is not sufficient for you and you still want to change the theme and do not want to restart then you should install this theme.

Once you install this theme, you will not note any change (Don’t forget to restart after installing the theme.)

The best part about the viewer is the ability to display gif inherently. Worth a look if you are using a lot of gif images.

bash script to run a command and take screenshot in every loop.

Couple of days back, I had posted a command to display a stop timer with bash and echo. There I had also put the following gif file:

<img class="size-medium wp-image-2555" title="bash screenshot for the script output" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/09/temp-300x170.gif" alt="bash screenshot for the script output" width="300" height="170" />

Here the tricky part was to capture the jpg&#8217;s to create the gif file.

Preparation:

1. Rename the terminal to aka – amit-capture

2. Execute the command once with the import command and check the output and jpg&#8217;s

Hard and Software requirements… can you beat this.

The other day, I was looking at OTRS Documentation and guess what, I found a requirement that I could not full-fill.  The requirement was for “Hard and Software”.

Can you full-fill this requirement?

F-Spot photo viewer – another tool with option to view the exif data.

bash – echo command with option to display the output on the same line.

Here is a nice little trick to display the output in the same line :

  <td>
    <div class="bash codecolorer">
      &nbsp;<span class="kw3">echo</span> <span class="re5">-ne</span> <span class="st0">"output\<span class="es1">\r</span>"</span>
    </div>
  </td>
</tr>

The trick here is simple, first we disable the <a class="zem_slink" title="Newline" rel="wikipedia" href="http://en.wikipedia.org/wiki/Newline">newline printed by <a class="zem_slink" title="Echo (command)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Echo_%28command%29">echo command with the &#8221;-n&#8221; option and then we enable the interpretation of the <a class="zem_slink" title="Backslash" rel="wikipedia" href="http://en.wikipedia.org/wiki/Backslash">backslash characters with the &#8221;-e&#8221; option. As the &#8221;\r&#8221; is used as <a class="zem_slink" title="Carriage return" rel="wikipedia" href="http://en.wikipedia.org/wiki/Carriage_return">carriage return which brings you to the start of the line without the newline (like in <a class="zem_slink" title="Typewriter" rel="wikipedia" href="http://en.wikipedia.org/wiki/Typewriter">typewriter), we will use the same to get the desired effect. So, if you wanted a stopwatch for a 100 seconds on the console then this simple bash <a class="zem_slink" title="For loop" rel="wikipedia" href="http://en.wikipedia.org/wiki/For_loop">for loop would do the same:
