Ubuntu- How to add a path to your path list in terminal (.bashrc file)
Posted on May 11, 2009 by Dude
Suppose you would like to have access to a particular path from within terminal. For example, if you have your executables in a folder called ~/my_program/bin you may want to have access to the executables from everywhere within terminal. One way to achieve this is to add that particular path to your path list in the “.bashrc” file. So, how to do that?
First launch a file browser and go to your home folder. You need then to edit the “.bashrc” file which is a hidden file in your home folder. You would therefore first need to make Ubuntu show your hidden files. In the menu bar on the top of the file browser window, select “View/Show Hidden Files” and check the mark . Here is a graphic for your reference:
Then find the file “.bashrc” file and open it with the text editor. You would then need to append a line or two to the file. For example, if you would like to add the path~/my_program/bin, you would need to add the following line to the file:
PATH=~/my_program/bin:”${PATH}”

Ubuntu- get rid of blank screen in MATLAB installed within Ubuntu
Posted on May 9, 2009 by Dude
There is sometimes a problem with the MATLAB in Ubuntu. The problem is that after installing MATLAB, you might get just a blank screen (blank GUI window) without any option menu, command line, etc. To solve this problem, find the file “environment” (the path is: /etc/environment). Add the following line to the file and try again:
export AWT_TOOLKIT=”MToolkit”
The problem should have been solved. If not, try restarting your computer.

Ubuntu- How to unrar rar files with ubuntu?
Posted on May 8, 2009 by Dude
If you have got a rar file (or other file formats not naively supported by Ubuntu’s archive manager- such as arj, 7zip, etc), you need to install extra packages so that Archive Manager can handle these file formats. For example, if you would like to unrar a file in Ubuntu, you need to install the package unrar. Open a terminal (command window) and simply issue this command:
sudo apt-get install unrar-free
for a non-free option, you can use:
sudo apt-get install unrar
You might be asked to give your password and then the package is downloaded and installed. After the package is installed, you can use the usual Archive Manager to unrar files.
Archive Manager (File Roller)- Taken from Ubuntu documentation- thanks to the contributors to the Ubuntu wiki
In general, following file formats are supported by the Archive Manager by default (from Ubuntu documentation- thanks to the contributors to the Ubuntu documentation wiki):
|
Format |
File extension |
Note |
|
Tar |
.tar |
|
|
gzip |
.tar.gz, .tgz, .gz |
Compressed .tar or compressed single file |
|
bzip |
.tar.bz, .tbz, .bz |
Compressed .tar or compressed single file |
|
bzip2 |
.tar.bz2, .tbz2, .bz2 |
Compressed .tar or compressed single file |
|
LZMA |
.tar.lzma, .lzma |
Compressed .tar or compressed single file |
|
ZIP |
.zip |
|
|
JAR |
.jar, .ear, .war |
|
|
CD images |
.iso |
Read-only |
These file formats are not supported by default and require additional packages to be supported (from Ubuntu documentation again): In the following table, it is mentioned that which package needs to be installed so that the Archie Manager can handle extra file formats.
|
Format |
File extension |
Note |
|
7zip |
.7z |
Needs the p7zip package, which doesn’t provide multi-volume support. To support password-protected archives, needs the p7zip-full package |
|
compress |
.Z, .tar.Z, .taz |
Needs the ncompress package |
|
shar |
.shar |
Needs the sharutils package |
|
lZO |
.lzo, .tar.lzo, .tzo |
Needs the lzop package |
|
LHA |
.lzh, .lha |
Needs the lha package |
|
ARJ |
.arj |
Needs the arj package |
|
ACE |
.ace |
Needs the unace package, providing read-only support |
|
RAR |
.rar |
Needs the unrar (non-free) or unrar-free package to extract .rar archives. |

Ubuntu- Quickly opening a shell terminal in any given place
Posted on May 7, 2009 by Dude
I have been always wondering why this feature is not pre-loaded into Ubuntu. Often times, one is in a particular location (path) within the file system (while using GUI file browser) and would like to open a terminal with the path defaulted to that particular location. I have been always thinking that this should have been as easy as right clicking and opting to open a terminal. Unlike some other Linux distros, it is not the case in ubuntu. But there is a work around for this problem. Just type:
sudo aptitude install nautilus-open-terminal
and the reuiqred package will be downloaded and installed. You probably would need to restart your computer before you can see the option. After restarting, open a GUI file browser and right-click. You should be able to see the option of opening a terminal in that particular path.

Logging as “root” in Ubuntu
Posted on October 8, 2007 by Dude
Have you ever wanted to Login as “root” in Ubuntu and have gotten the message that the “root” is not allowed to login? Actually, that is because loggin as “root” in Ubuntu is neither recommended nor necessary. Doing so can leave your computer more intrusion-prone and, besides that, it could be that you can mess up some files or make another accidental mistake. Most of times, any administrative command can be issued just by using “sudo” in front of the command. However, in very exceptional cases it is really more convenient or even necessary to login as “root”. Then what? It is actually possible to login as root in Ubuntu. But, again, I do not recommend you to do so. As I said, it is almost always unnecessary and dangerous.
Well! if you are still here and really want to know how to login as “root” in Ubuntu (at your own risk), you need to know that two steps are necessary to enable GUI “root” login. First, a password has to be assigned to the “root” account which can be done by issuing the following command in a terminal:
sudo passwd root
Then, if one really wants to enable the GUI “root” login (not recommended, think again!), following command can be used:
gksu gdmsetup
A GUI opens. In the security tab, there is an option which can be used to allow local system administrator login. The option needs to be checked in order to allow the “root” login. I highly recommend you not to do so and if you are keen to do so, do not let it to remain that way and bring the system to its default state AS SOON AS POSSIBLE.
