sakura – Reaaly good terminal with very few dependencies.

I was searching for something in the Fedora repos and found a really good terminal, sakura. Its very much like Gnome-terminal. I did not find much difference other than using less memory.

To install:

  <td>
    <div class="text codecolorer">
      sudo yum install sakura
    </div>
  </td>
</tr>

and the details of the package:

Name        : sakura

Version     : 2.3.8

Release     : 1.fc14

Size        : 137 k

Repo        : installed

Description : Sakura is a terminal emulator based on GTK and VTE. It’s a terminal emulator

with few dependencies, so you don’t need a full GNOME desktop installed to

Ranking of the most frequently used commands

Lets take a quick look at how to get the most frequently used commands on you shell. So what we need to do is this:

  <td>
    <div class="text codecolorer">
      history | awk '{print $2}' | awk 'BEGIN {FS="|"}{print $1}' | sort | uniq -c | sort -n | tail | sort -nr
    </div>
  </td>
</tr>

So, how did we arrive at this and will this always work? No it might not always work. A typical example is where HISTTIMEFORMAT variable is set. In that case, if you check history, you will see that after the number column we have time and date in the specified format, in which case, you will get wrong information from the above command. Anyways, forgetting these special cases, lets go to how we got this command:

bash math

fork a new process in perl

I was doing something today and found that I require to fork a new process in perl. Now I had never done this earlier, so I did not know how to do this.

First some background :

I was doing some program very similar to http server, where the script accepts some input through a socket and then processes the same. In doing so I was seeing that the script was taking some time in processing the input and thus was not processing the second request until the first one was completed. Simple solution, fork the process.
