I need a program to permanently remove files from my system similar to File Shredder

Solution 1:

There is a tool on Linux called "wipe", and you can install it by the following command:

    sudo apt-get install wipe

This allows you to securely render a file you want deleted unrecoverable (via reasonable attempts at recovery). Here is the manual for wipe if you want to read any information on it. It is also a good idea to read the man page of wipe straight after installation. This is done by:

    man wipe

Solution 2:

There's also a tool called BleachBit, which you can find in Ubuntu Software Center. Not only does it wipe free space but also has quite a lot of options for cleaning up the system.
