But there’s a problem. Sometimes Linux can go extremely up to
the extent that it can do serious damage to the system. Linux
system doesn’t even ask the user for confirmation once the
command is given and simply performs its task

to use it only if you are good at giving commands and have
in-depth knowledge of Linux commands list.
5 Most Deadly Linux Commands
1. rm -rf /
This command will Delete Everything from your computer. It is a
combination of three keywords. rm will remove all the files
followed by this command. -rf will run rm command in the more
effective way and will remove all files and folders inside the
specified folder without asking confirmation from the user. “/”
will start removing the data from the root directory and will
delete everything from the computer including the data of
removable media.
2. :(){ :|: & };: Sh
This command creates a shell function, which once gets
initialized starts to create multiple copies of itself. It
results in taking quickly all the memory and power of CPU. It
makes computer freeze or not responding. This is also known as
Denial Of Service Attack.
3. mkfs.ext4 /dev/sda1
This command will format the hard disk. This command is again
composed of two keywords. mkfs.Ext4 command will create a new
ext4 file system on the following device where this command will
get executed. /dev/sda1 specifies the 1st partition on the first
hard disk which is probably in use by the user. Similarly, This
Command > mkfs.ext3 /dev/sdb2 will Format the second partition
on the second hard disk with ext3 File system.
4. /dev/sda
This command will Write Any content Directly to a Hard Drive.
This command will execute normally as other commands in Linux
do. But the output of this command will directly be sent to the
file system (NTFS or FAT ) of the Hard Drive. It will result in
damaging the file system of the computer.
5. mv ~ /dev/null –
This command will turn your home directory into a Black hole.
Moving any of your content and data to following path :
/dev/null means you want to destroy it. It means /dev/null is a
black hole where once anything sent , can not be recovered back.
