Every time I close my terminal and reopen it, simples command(e.g. ls) doesn't work. It shows the following error,

irfan@irfan-Y500-Elementery:~$ ls
Command 'ls' is available in '/bin/ls'
The command could not be located because '/bin' is not included in the PATH environment variable.
ls: command not found

I have to execute the following command export PATH=/usr/bin:/bin every time to correct this error,

irfan@irfan-Y500-Elementery:~$ export PATH=/usr/bin:/bin
irfan@irfan-Y500-Elementery:~$ ls

Blender  Downloads        export           output.pdf  sudo
Desktop  Elementary Luna  jmonkeyplatform  Pictures    Templates

My questions is, why I have to do it every time? and what do I have to do to solve the repetition.

My /etc/environment files contains the following,

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
CLUTTER_PAINT=disable-clipped-redraws:disable-culling

Note : I am using ElementaryOS(based on Ubuntu 12.04)

Edit 1:

echo $PATH returns /usr/local/jre1.7.0_51/bin:

I followed this answer to set java path.

I added

PATH=/usr/local/jre1.7.0_51/bin:
export PATH

to my /home/irfan/.bashrc file. I guess this caused the problem

Say I want to install Codeblocks(C/C++ IDE) using Ubuntu Software centre. But, if I do that I will install version 10, when I can have version 12 if I download package from Codeblocks website. The same happens with Eclipse. Ubuntu software centre has version 3.x and I can have 4.x from Eclipse website.

Question is why ubuntu software centre doesn't have the latest version of a software? Is this the lack of interest of developers, not to update their latest release on ubuntu software centre? or something else?

I am trying to recover an accidentally formatted partition using testDisk,

After selecting the partition[pic 1] and selecting Undeleted[pic 1], it says, No deleted file found.[pic 2]

I know it's a silly question, but I just want to make sure that those data are really out of reach. Or is there anything I can do to recover them? :(

I tried to repair my partition table using bootrec.exe/FixMBR & bootrec.exe/FixBoot, can this be the reason why testdisk can't work anymore? I haven't written anything on that partition.

Is there any low level approach to retrieve all the lost data?

Here in the screen shot, there is a window and terminal open.

Problem

I am running on Ubuntu 10.04(kernel 2.6) LTS 64bit LiveCD session, and trying to run testDisk to recover my another formatted partition.

But, whenever I run the 

sudo testdisk_static

command, it says, command not found!

As you can see in the picture, this file(testdisk_static) exists. if i double click it nothing happens. Its not running from terminal either.

Why this file doesn't run? What to do in this situation?

Here is the situation.I am a duel windows ans ubuntu user. Accidentally I formatted the C partition(root partition of windows).

Now I ran several live ubuntu sessions from CD. And found a way to recover my formatted C partition using testDisk.

testDisk is supposed to revert back my partition to its original state, but only if i hadn't written anything after the format.

My question is, does the live session write anything on the C partition(boot partition) ?

Sometimes i tried to remotely access the pc, while the live session was running. I had to change the host name, root password and other network setting..does this activity may result is some data written on the formatted partition?
