Linux Commands that should be avoided

[vineetrocks2005]

I am presenting some of the most fatal command in Linux, that could harm your OS within no time. Please don’t try these on your Linux distribution.

1. mv /home/yourhomedirectory/* /dev/null

It is a simple command that will move the contents of your “home” directory to a “null” directory (a directory that never existed), hence you will never see that files again.


2. ){:&};:

This command will execute a large number of processes until your system hangs. Also known as forkbomb, this command often leads to corruption of data.

3. mkfs.ext3 /dev/sda

This will simply formats the device that is mentioned after the “mkfs” command.

4. rm -rf /

And last but not the least, this command will forcefully delete all the files inside the “root” directory.

Well as for second one, I cant really put those smiley in there :/

And most of them are only fatal when used under root account.

Any day, it's a noob's delight to experience them accidentally or amusingly.

echo "Gautham is a n00b at bash scripting"

echo "Don't execute this command as root"

Try running it as root
