7-deadly-linux-commands

You want to learn about Linux, start from learning what not to do. <a href="http://www.junauza.com/2008/11/7-deadly-linux-commands.html" target="_blank">Here is one for the starting point.

So moral of the story is if someone asks you to do something and you dont know what that command will do, then dont do it. If your inner thing does not allow you not to do it, do it with all the care you can take. May be a backup and most importantly &#8221;DONT USE ROOT LOGIN IF U DONT HAVE REASON TO USE IT&#8221;. BTW there are couple of more articles on these kind of advices but the best way to save yourself is to educate yourself on the outcome of the command you are executing.
