Some malicious users can post in a forum or IRC chat dangerous commands that destroy the system, or data.
We must be careful and know the functioning of these commands to avoid using them without thinking.
rm -rf /
This command simply clears all files on your hard drive. Once deleted, files can not be recovered.
mkfs.ext3 / dev / sda
Mkfs is a command used to format hard drives. Here it will erase data on the disk / dev / sda.
: () {: |: &};:
This command is actually a fork bomb. When launched, your system will be forced to create process until the memory is full. Which forces you to make a sudden stop and can cause system corruption.
mv ~ / * / dev / null
Move a file or directory to / dev / null returns to put in the trash.
/ dev / null is the equivalent of the final basket, any files sent to this event will also be deleted. And this without possibility of restoration.
dd if = / dev / zero of = / dev / sda
This command will write zeros in all blocks of the hard drive and results in total data loss. That is to do a full format.
