  • Some wget tricks

    Some wget tricks

    Posted on December 1, 2009 | 1 Comment
    The wget is a command line utility that can download files from web servers and FTP servers.
    For example , you can download the DVD image of Karmic Koala using the following command.

    $ wget http://cdimage.ubuntu.com/releases/9.10/release/ubuntu-9.10-dvd-i386.iso

    If an FTP server requires a login and password, you can enter that information on
    the wget command line in the following form.

    $ wget ftp://user:password@ftp.example.com/path/to/file

    You can use wget to download a single web page as follows:

    $ wget http://unixlab.blogspot.com

    A file named index.html will be created in your current directory

    If you open this index.html in a web browser , you will find some of the links broken especially images. . To download all the images and other elements required to render the page properly, -p option can be used.

    $ wget -p http://unixlab.blogspot.com

    This will create a folder named unixlab.blogspot.com with index.html in it.

    But if you open the resulting index.html in your browser, chances are you will still
    have all the broken links even though all the images were downloaded. That’s because
    the links need to be translated to point to your local files. So instead, do this:

    $ wget -pk http://unixlab.blogspot.com

    Sometimes an HTML file you download does not have an.html extension, but ends
    in .php or .cgi instead. . If you wget files from such a site , your browser will complain when you try to open the file. To solve the problem , you can ask wget to append .html to such files using the -E option:

    $ wget -E http://unixlab.blogspot.com

    I use the following command line to keep a usable copy of the website on my hard disk.

    $ wget -mEkK http://unixlab.blogspot.com

  • Enhancing terminals with byobu on Ubuntu 9.10

    Enhancing terminals with byobu on Ubuntu 9.10

    Posted on November 12, 2009 | No Comments
    Byobu is a Japanese term for decorative screens . A Japanese byobu screen looks as below.



    You can achieve similar decorative effects on your gnome terminal or xterm , or Konsole with Byobu software available from ubuntu launchpad. Infact, the new ubuntu 9.10 ships it by default. On earlier versions of ubuntu you can install byobu from the PPA here.

    On my jaunty box , I added the following to /etc/sources.list and imported the key form the PPA and installed it via apt,

    For trying out byobu , open a terminal and type

    $ byobu

    your terminal will immediately change to the following screen.



    The bottom line on the above picture indicates the present status of your system. It displays several useful parameters. Byobu can be customised to display several other informatiin.

    Infact ,byobu is an enhancement to GNU/Screen. So, all commands applicable to GNU/ screen will work with byobu. If you are not familiar with screen look at this page for some additional information

    Most of the settings of byobu are stored in a hidden directory named .byobu under your home folder. Most ot these settings can be modified from byobu itself. For customising byubu, press F9 . You will get the following screen.


    You can change the look and feel of your terminal as shown in the screen-shots below.




    For me the status notifications on the last line is very useful For adding additional parameters Press F9 and select status notifications , you will get the following screens. Choose whatever parameter you want to display as your default status line.





    To start byobu automatically when ever you launch a terminal on Karmic Koala desktop, select
    the last option as shown below. ( Be careful as screen sessions can become background processes. I suggest you GNU/screen documentation )


    and press enter.


    Now click on edit->> Profile Preferences-> Title and Command on your gnome-terminal and tick Run command as login shell.


    Byobu will be launched automatically next time when you start a terminal.

  • Yakuake : A pull down terminal for your desktop

    Yakuake : A pull down terminal for your desktop

    Posted on August 1, 2009 | No Comments
    If you are addicted to doing things on terminal, yakuake is your friend. Yakuake is a KDE application and it takes the standard KDE Konsole and changes it to a drop-down, on-demand terminal over your desktop and applications. This is a very handy little application. ( It resembles the classic game quake in showing the console screen on your desktop.)

    To install, simply use

    $ sudo apt-get to install both konsole and yakuake

    If yuo are on Ubuntu open up a terminal and run yakuake from the terminal.
    It will prompt you with the following screen .



    Yakuake is prompting you to set a short cut key .The default is F12 . However on my Ubuntu desktop F12 is bound to search. So I clicked on the button and changed the default key to F10.
    Press ok and save the configuration.
    Now if you press your short cut key , yakuake terminal will pop up. If you press it again , it will hide itself. The appearance and behaviour of yakuake can be controlled. from its menus. You can access the menu by clicking on the down arrow symbol on the bottom right corner of yakuake window. Yakuake recognises almost all settings of konsole the KDE terminal.

  • Stupid Geek Tricks: Watch Movies in Your Linux Terminal Window

    Stupid Geek Tricks: Watch Movies in Your Linux Terminal Window

    Posted on February 22, 2009 | 1 Comment

    In these days of high definition videos everywhere (even YouTube), only the truly geeky would decide to watch their movies in ASCII text in a terminal window. The surprising thing is that some videos are even fairly watchable.

    image 

    I’ve found that cartoons work best because of the limited detail. Even more importantly, the series finale and (probably) last ever Futurama movie is coming out Tomorrow on DVD! You can pre-order Futurama: Into the Wild Green Yonder on Amazon.

    Watch Movies in ASCII

    The first thing you’ll want to do is make sure that mplayer is installed, which is easy enough from the command line:

    sudo apt-get install mplayer

    Then, to actually watch the movies from a terminal window, use the following syntax, replacing MovieName with the filename of your video.

    mplayer -vo caca MovieName.avi

    The “caca” command is actually the color text driver – you could also use ” -vo aa ” instead for black & white, but that would just be silly.

    image

    These screenshots don’t really do it justice – it’s seriously just as bad when you’re watching.

    image   

    Sequences with a lot of contrast work better…

    image

    And it wouldn’t help to sit about 8 feet back from the monitor.

    Now that was truly a Stupid Geek Trick!
