    Terminal based drop box installation Procedure

    How to install dropbox from terminal in Ubuntu 12/13/14

    Dropbox is a cloud which became a handy-tool, especially for researches, to store online their research work. 
    The demand was further enriched with the closure of ubuntuOne, which used to be favorite online cloud storage.

    Here follows the procedure for the installation of dropbox:

    Step 1: For 32 bit machines:

     cd ~ && wget -O - "" | tar xzf -

    For 64 bit machines:

    cd ~ && wget -O - "" | tar xzf -
    Step 2: Next, run the Dropbox daemon from the newly created .dropbox-dist folder.
    NOte: This procedure was tested on Ubuntu 12.04,Also, this procedure will work on any another Linux.

    shortcut virus remover for USB (pen) drives

    If you are facing the problem of all (or partially) files in your portable USB drive becoming shortcuts, then here is a one step solution for any TechLAYMANs.
    Note: Don't click the shortcut file directly, before this solution.

    solution 1:traditional solution
    Step 1: Download this portable shortcut virus remover file.
                 This is java file. So, it works on all operating systems
    Step 2: Place this downloaded file in the effected USB drive.
    Step 3: click on it to run, and then give Enter.

    solution 2: Terminal based solution

    Step1: press windows key+R, enter cmd, then enter. Then, Command prompt will open.
    Step2: Initially find the effected removable drive alphabet (E or F or G,...).
                Then type E: (for Removable drive E),then give enter.....Now, you will go to that drive.
    Step 3: type attrib -r -s -h *.* /s /d, followed by enter.
    Step 4:  Then type del *.lnk
            Now the pen(usb) drive is ready to use.

    WOW! the simplest process completely recovers your missing data. Have fun!!!

    For any further doubts, mail me.
