How to install programs on USB stick

By Jovel Sam on 00:08 in pendrive, Ubuntu, USB

Applications like UNetbootin from the default Ubuntu repositories, Will allocate space used to preserve files across reboots.

The default size of the persistent storage space is 0 MB, but it can be changed from the default size at the same time that you create the Ubuntu live USB.

In the below screenshot the persistent storage space is 4GB on an 8GB USB flash drive with one FAT32 partition ( /dev/sdd1 ).

UNetbootin

The persistent storage space enables you to install software or save files on an Ubuntu live USB persistently across reboots. The persistence feature is not supported on Ubuntu 16.04 and later.

UNetbootin is compatible with Windows, Mac and Linux, however UNetbootin has been dropped from the Ubuntu 18.04 repositories.

5 Deadly Terminal Commands in Linux

By Jovel Sam on 02:35 in Hard Drive, Linux, Terminal, Ubuntu

Terminal is powerful than Command Prompt. It won't ask your confirmation if you type a deadly command. Newbie linux users can be easily fooled by these code spreading as trolls via internet. So you must be aware of these code that will destory you computer.

1. rm-rf /

this code deletes everything on your computer. This formats everything possible including Hard drives and connected storage devices.

rm - deletes the following files.

-rf - deletes all the files and folders inside a particular folder.

/ - this instructs rm to start from the root where all your files are located.

2. :(){ :|: & };:

this one is a kind of virus that defines a shell function. It has the ability to replicate itself to many copies which may then eats up your cpu time and memory.

3. mkfs.ext4 /dev/sda1

this one is same as formatting C drive in windows. this will format your first partition and replace them with a new file system.

4. mv ~ /dev/null

This code makes your home folder disappear. in other words will move your home folder into a black hole.

mv - means to move folder or file.

~ - this indicates your home folder as a whole.

/dev/null - Destroys everything.

5. dd if=/dev/random of=/dev/sda

This code copies junk files in to hard drive.
