Install Firefox 4 on Linux Mint Debian Edition (LMDE)

I am testing out Linux Mint Debian Edition (LMDE) and wanted to benefit from Firefox 4 and all its speediness.  It’s not available in the repositories and since LMDE uses Firefox and NOT Iceweasel, you really can’t install it from the Mozilla Debian repository.  So, I decided to manually install things.

Normally I don’t like to manually install things outside the repository because when updates are pushed, there is no upstream source to differentiate from…so your chances of running outdated software increase unless you are vigilant.  Luckily, I consider myself vigilant.  Unfortunately, I’m not as vigilant as I consider myself to be…so I’ve added in reminders for myself on my Google calendar to check for Firefox 4 updates.

So, here’s how to get Firefox 4 onto your LMDE desktop…First, uninstall the version of Firefox you have using Synaptic or the software center.  Open a terminal up and let’s get started.

Create a temporary directory to house a downloaded and unzipped Firefox:

cd ~/ && mkdir tmp && cd tmp/

Next, let’s download and unzip it (please note this is for en-US version only…you’ll have to adjust the URL for diff. languages):

32bit

wget http://releases.mozilla.org/pub/mozilla.org/firefox/releases/latest-4.0/linux-i686/en-US/firefox-4.0.tar.bz2

64bit

wget http://releases.mozilla.org/pub/mozilla.org/firefox/releases/latest-4.0/linux-x86_64/en-US/firefox-4.0.tar.bz2

Now let’s unzip and extract it:

tar -xvjf firefox*.tar.bz2

Now let’s move the newly extracted items to /usr/local so it can be used by the system:

sudo mv firefox /usr/local/firefox4

Now we need to create a link so that applications calling firefox 4 access it correctly:

sudo ln -s /usr/local/firefox4/firefox /usr/local/bin/firefox4

Ok, the hard part is done…but you don’t have a menu entry for it nor a shortcut you can execute.  Let’s do that now.  Right click your mint menu and choose “edit menu”.  Now, select the “Internet” menu in the left hand pane.  Click the “New Item” button.  The following window will pop up…fill it in with the information contained in the picture below:

The command line should be (remember the link we made above? let’s use it!):

/usr/local/firefox4/firefox %u

launcher properties

Notice in the picture above the Firefox icon is present…yours most likely isn’t.  In order to set the icon, click the area where it appears above and then select the following image:

When you’re finished, click close.  Firefox 4 should now appear under “Internet” in your Mint Menu.  You can now right click that item and add it to your favorites if you wish.

Now let’s make sure you list Firefox 4 as the default web browser for Gnome.  Do this by opening up the control center in the Mint Menu.  Select “Preferred Applications” inside the control center.  Make sure that you choose ‘custom’ in the drop down menu shown below and the path for the command will be the same as it was for your launcher but instead of a %u you can use a %s at the end of the command (as shown in the picture below):

preferred applications

That should be everything you need to have a good Firefox 4 experience in LMDE.  To uninstall things, you can simply delete the menu items and then delete the directories we created during the install process.

Hopefully this will help those of you out there who want Firefox 4 on your LMDE install!

Back to the Basics with Debian

Sometimes, you just have so many problems with the distribution you’re running that you have to wipe it out with a clean slate. I did that this past week and am now using Debian.

With using Debian there comes a feeling of being back to the very basic of Linux distros…much in the same way when you use Arch…it just feels plain, unencumbered, and basic and there is a feeling you get when build something from nothing…you start with a kernel and just enough CLI tools and create your house…then live in it.

It feels good to be stable. It feels good to not have to worry about programs crashing, the net disconnecting, or not being able to install programs.

People like to ride the unstable or testing route with most things out there…as I move forward in my Linux journey, I find myself looking to be less and less cutting edge and more and more stable. Plus, if there is a program out there that needs updating…backports are always a good way to get them.

I’m enjoying my new digs and will look to getting back into the swing of posting enjoyable articles and how-to’s in the upcoming weeks.

Unity Linux Gets a Sponsor with Host Color!

Good news to all of you out there that watch the project I’m involved with called Unity Linux.  What is Unity you ask?  Allow me to give you some background:

Unity Linux is a small Linux core based on Mandriva Linux.  We whittle down Mandriva to a small base desktop to provide users with ‘just enough graphics’ to be able to login and create their own distribution of Linux with the liveCD project which lies at the heart of Unity Linux.  We’ve replaced some of the common things like uprmi with the Smart Package Manager and we’ve moved on past RPM version 4 to RPM version 5.  Version 5 gives us some really cool features as well as speed enhancements across the board.

If you’re in the mood for Mandriva goodness (control center) without the extra stuff…give Unity Linux a try as a cholesterol free Mandriva.

In February of this year, Unity Linux turned 2 years old.  With this milestone on the horizon, we were approaching the time when our hosting service was coming due for another large chunk of change.  I began to seek out different hosting plans and price them and our developers started talking fund raising.  In January, I approached a hosting company named Host Color about the possibility of sponsoring Unity Linux via providing a hosting plan for them…to my delight, they were more than happy to provide for us!

I approached Host Color because they have been a sponsor of Yet Another Linux Blog for well over a year now helping the authors here bring excellent how-to’s and editorials about Linux.  Now Host Color has offered hosting for Unity Linux and given us a fine place to hang our hosting hat.  So, please join me in thanking Host Color for providing us with our new home!

Disillusioned by the Community

There are times when I don’t want to admit that I use and love Linux.

It’s true…at times, I’m embarrassed to tell people that I’m part of the community as a whole.

You may wonder when these times are…right now is one of those times.  I despise infighting found in free and open source software…specifically, I really don’t like it when people have one sided experiences and apply their experience to ALL areas of Linux and open source software.  Case in point is this blog post on KDE 4.6 experience in Ubuntu.  For everyone out there, please be advised that Ubuntu is not equivalent with ALL Linux.  In fact, Ubuntu does Gnome very well…but it doesn’t do KDE well at all.

If you truly want to know what KDE 4.6 is like, you need to go with a KDE specific distribution like Mandriva and ride that cutting edge.  I can guarantee you won’t be greeted by crash handlers and all sorts of nonsense that you’ll get inside Ubuntu when you install KDE along side of your Gnome install.

Posts like the one I linked to above make me angry…it’s like driving a Volvo compact car and then dismissing every other car company that makes a compact car as equivalent the experience on the Volvo.  To me, you need to drive each implementation (each companies interpretation) and make an informed decision as to what you find.  Taking a test drive of a Volvo compact and then bad mouthing all compact cars is ignorant…and in my opinion, that is what the person above does with KDE 4.x

I’m a staunch defender of KDE 4.x and I’ve blogged about ignorance surrounding it in the past.  Not all gripes about it are ignorant…but a majority of people’s problems they have with it are simply people band-wagoning together to trounce something because it’s cool to do so.  Much the same is M. Night Shyamalan’s Airbender movie…people talked so much crap about the movie and him as a director, I thought that the movie was going to be the worst movie of all time.  It wasn’t near as bad as people were making it out to be and Shyamalan isn’t the worst director out there by any means.

I think overall, KDE 4.x has become the M. Night Shyamalan of the Linux world…a very talented director(project) that everyone was accustomed to making great movies(desktops) that doesn’t want to be pigeon holed into fitting what others feel it should fit.  KDE 4 is not KDE 3 and for good reason.  It’s being coded and made into something different yet subtly similar because it’s 2011 and not 1996.  If you don’t like it, don’t use it.

IF you don’t use it…don’t trash talk it.

If you want an HONEST representation of it, go to a distribution that prides itself on providing a good implementation of it.  Saying “Ubuntu is the most popular and people are going to try it out on Ubuntu” is wrong…because I don’t know of many end users that will enable a PPA repository and possibly jack up their Gnome install to give it a go…when they can just pop in a Live CD and give it a try….I think the poster of the blog entry above forgot about the magic of Live CD’s for his ‘review’.  It’s too bad that he feels Ubuntu’s lack of attention to all things KDE are representative to KDE as a whole…and it’s too bad his attempt at ascribing this notion comes off as troll-like.

I don’t use Ubuntu at all yet you don’t see me trolling the Ubuntu boards talking about how crappy I feel it is.  If you use Linux you are a part of the Linux community as a whole.  This community encompasses all distributions and all desktop environments.  You have a responsibility therefore; if you want to see Linux succeed, be tolerant and understanding of opposing distros/desktops. Talking trash about other opposing opinions is irresponsible and juvenile.  I hope someday people take this inherent and implied cordiality to heart.  Until then, we have posts like the one above…whether inadvertently geared to bash KDE or absolutely geared to bash KDE…it nonetheless bashed it.  I hope we can grow past things like this in the future.

Chasing Your ‘Tail’ With Linux

‘GNU tail’ is a small utility which prints (by default) the last 10 lines of any file. This an amazing piece of software not only allows you to see the last part of a file but also enables you to monitor a file’s changes without opening the file.

‘tail’ can be used alone or can be combined with other commands like ‘grep’, ‘ls’ etc.

To use ‘tail’, let’s first create a text file. You can create the file by issuing following command in terminal;

touch my_file

Now open my_file with your favorite text editor (nano in my case) and write some lines. For this article, I have written the following 15 lines;

this is the 1st line
this is the 2nd line
this is the 3rd line
this is the 4th line
this is the 5th line
this is the 6th line
this is the 7th line
this is the 8th line
this is the 9th line
this is the 10th line
this is the 11th line
this is the 12th line
this is the 13th line
this is the 14th line
this is the 15th line

Now issue the following command in terminal;

tail my_file

It will print the last 10 lines which would be the “this is the 6th line” through “this is the 15th line”.

You can control the number of lines which ‘tail’ will print. You can either increase or decrease the number of lines. For example, if you want ‘tail’ to show only last 3 lines, you can do this by issuing the following command;

tail -n 3 my_file

Now it will print only last 3 lines. You can use any number of lines instead of 3. Or you can use a plus sign like;

tail -n+7 my_file

‘tail’ will start printing from 7th line to the end of the file.

You can view the desired file with respect to size. Issue the following command in terminal;

tail -c 14 my_file

And it will show the output of last 14 bytes. In my case, the output was;

the 15th line

‘tail’ not only displays the static output of a file but it can also monitor the file for changes. A ‘-f’ option is used with ‘tail’ and it starts acting like a monitoring tool which not only displays the last few lines but also constantly updates the output as the file changes. Here is a very popular example;

tail -f /var/log/message

‘tail’ will print the last 10 lines of ‘message’ file. If you now plug-in you USB stick, you will notice that the change in ‘message’ file will instantly be reported by ‘tail’. To release the cursor press Ctrl+c.

There are many other useful options which you can use with ‘tail’ like;

tail -q my_file        # never output headers
tail -v my_file        # always outputs headers

You can combine ‘tail’ with other utilities like ‘ls’, ‘grep’, ‘head’ etc.

You can combine ‘tail’ with ‘grep’ to get lines with some specific ‘word’.

tail -n 5 my_file | grep 14

It will print only those lines out of last 5 which contains the word ’14’. In my case the output was:

this is 14th line # ’14’ will be highlighted

‘tail’ can also be combined with ‘ls’ to get the list of last few files/folders. For example, if you issue the following command;

ls -l | tail -n 2

It will give a long listing of files/folders but will show the last 2 entries of the working directory.

These are just two examples of combining ‘tail’ with other utilities. There are countless examples of combination of ‘tail’ and other softwares.

‘GNU tail’ is a very handy tool. It can output any amount of data depending upon the options used. It makes the work of an ordinary user much easer and helps him/her find information in files more efficiently. To become an expert in Linux, this is a mandatory utility over which a user must have complete mastery. Hopefully, this tutorial gets you started chasing your tail!

Using ‘Alias’ in Linux

There comes a time in every Linux users’ life when you will open the Terminal more often than not because you have realized that it is faster, more efficient and more powerful than GUI (Graphical User Interface).  You’ll have started to learn more and more commands and now feel more comfortable with command prompt.  The command prompt is all about commands – short commands as well as long commands.  If you are like me then you may not like to type the long commands (or even small commands) :)

You may be thinking about some way to avoid typing commands over and over. Enter the ‘alias’.

The ‘alias’ tool is a way to make the complicated things simple (and simple things simpler). You can use ‘alias’ instead of long (or even short) commands.  Now let’s see how the ‘alias’ works.

‘alias’ can make difficult and lengthy commands easy. The general format of ‘alias’ is:

alias Any_Word=”Command”

It means you linked an existing command to a (New) Word. This ‘Any_Word’ may contain anything – any alpha-numeric symbol, ‘Any_Word’ as well as ‘Command’ are interchangeable and can be used for the same purpose.

Simple Commands Made Simpler

As an example, ‘ls -l’  is used for listing directory contents in ‘long listing format’. This ‘ls -l’ can be replaced with a simpler alias. You can set the ‘alias’ for ‘ls –l’ as follows:

alias ll=”ls –l”

Now you just have to type ‘ll’ (without quotes) to get ‘long listing format’.

Or if you frequently misspell ‘ls’ as ‘sl’ and don’t want to install ‘sl’ package, then, you can use the following alias:

alias sl=”ls”

Now, whenever you type ‘sl’ in terminal, it will give you same results as ‘ls’.

Now consider even simpler example. To close a Terminal (or logout), you have to type ‘exit’ in Terminal. This ‘exit’ command can be made even simpler by using the following ‘alias’:

alias x="exit"

Now, you only have to type ‘x’ in Terminal to ‘exit’

Other examples of ‘alias’ are:

alias cp="cp -iv"
#make copy operation interactive and verbose
alias rm="rm -iv"
#make remove operation interactive and verbose
alias mv="mv -iv"
#make move operation interactive and verbose

Make Package Management A Bit Simpler

If you use Debian (or its derivatives) then you will be familiar with APT.  It is an excellent package manager.

In Ubuntu, to install software using APT, you have to use the following command:

sudo apt-get install <sofware_name>

It is a long command and consumes a lot of your time and energy :)

You can shorten this command by using ‘alias’.  Issue the following command in Terminal:

alias Install=”sudo apt-get install”

You can obviously use your own word instead of ‘Install’.

Now, you just have to type:

Install <software_name>

to install the (same) software. Simple, isn’t it?

You can simplify other aspects of APT. For example, you can use the following ‘alias’:

alias Remove=”sudo apt-get remove”

to uninstall a software.

Some other examples of attaching APT with ‘alias’ are:

alias Update=”sudo apt-get update”
alias Upgrade=”sudo apt-get upgrade”
alias Search=”apt-cache search”
alias Autoremove=”sudo apt-get autoremove”
alias Autoclean=”sudo apt-get autoclean”
alias Purge=”sudo apt-get remove –purge”

and so on…

A Very Interesting ‘alias’ For A Difficult Keyboard Button

On some keyboards, the dot (.) button is at very difficult position and if you have to use it more than once, it becomes even more difficult.  That’s why ‘cd ..’ is the command which I mistype the most.  This complication can be easily removed by using following ‘alias’ (you can use any other word instead of a dot):

alias .=”cd ..”
alias ..=”cd ../..”
alias ...=”cd ../../..”
alias ....=”cd ../../../..”

Using Internet From Terminal

If you regularly use lynx to browse the internet in terminal then you have to type long urls with lynx to visit the web pages.  You can simplify these long urls by using ‘alias’:

alias Google=”lynx http://www.google.com/”
alias Yahoo=”lynx http://www.yahoo.com/”
alias yalb =”lynx http://linux-blog.org/”

and so on…

Now just type Google, Yahoo or yalb to visit the respective web sites.

Simple ‘alias’ For More Complicated Commands

Long commands are not only difficult to remember but also take more time to type; when you have to use them on daily basis, you become frustrated when typing them again and again and again… So, ‘alias’ are more suitable for long and complicated commands.

Let’s consider an example.

To find the top 10 largest files in your system, you can set the following ‘alias’:

alias top10files=”find . -type f -exec ls -sh {} \; | sort -n -r | head -10”

You can even mix different commands with ‘alias’.  For instance, if you regularly use ‘tail’ and direct its output to file to later view that file, you can set a very simple ‘alias’ to do this cumbersome operation in 1 word:

alias Tail=”tail /var/log/messages > hello.txt;cat hello.txt”

Now just enter ‘Tail’ and viola! All is done at once.

You can use any file with tail and direct its output and you can even use ‘nano’ or ‘vi’ to view/edit its output.

Here’s another example… ‘alias’ to connect to a remote server:

alias any_name=”ssh <remote_server_address> -l <username> -p <port>”

You can even create ‘alias’ for your bash scripts, like:

alias clc=”sh /home/user/myscripts/calc.sh”

Now that you have set a few different ‘alias’  you might want to check that which ‘alias’ are set on your system.  To do that, just issue the following command:

alias

and it will list all the set ‘alias’ you have.

To remove an ‘alias’, just issue the ‘unalias’ command, like:

unalias Google

and now typing Google in terminal will do nothing (as it was set with lynx).

To remove all the ‘alias’, issue the following command and all the ‘alias’ are gone:

unalias –a

We have discussed the way of setting the ‘alias’ for different kinds of commands.  But setting ‘alias’ in this way be temporary.  When you reboot you PC, all the ‘alias’ which you have set will be gone.  This does not mean that you have to set all the ‘alias’ every time you boot your PC.  If you have set an ‘alias’ and you liked it so much that you want it to permanently reside in you PC, just add this alias in ‘.bashrc’ file in you home directory. For example, if you want ‘alias’:

Install <software_name>

to permanently reside in your PC then user your favorite text editor and add the following line in your ‘~/.bashrc’ file:

alias Install=”sudo apt-get install”

Now this ‘alias’ will not vanish into thin air when you reboot your PC. Only those ‘alias’  which are listed in ‘~/.bashrc’ file will be permanent.

This guide is just a preview about ‘alias’.  It is just about basic ways of using ‘alias’ to make your life simpler.  ‘GNU alias’ is a tool which can simplify your life immensely.  But unfortunately this tool is not given the attention it deserves.  In short, it is such a powerful tool that if you give it proper time, it can make you forget typing :)
