sudo nautilus adalah perintah andalan saya. tidak tahu kenapa saya suka sekali dengan perintah ini. terkadang untuk merubah sebuah file harus dengan root access. dulu saat masih belum begitu paham (sekarang juga masih nggak mudeng) main di localhost bingung mengubah file yang hanya bisa diakses root.

jika login as root bahayanya dijabarkan di http://ubuntuforums.org/showthread.php?t=716201

Isn’t knowledge power? What’s the harm in having these tutorials posted?
Let’s say you put your money into a bank and the bank gives you an ATM card allowing you to withdraw money if you enter a password in. You decide, however, that you don’t want to have to enter a password. You’d rather just be able to put the card into the ATM machine and withdraw cash with just the card and no password. Let’s also say that there is a way to tweak the card so as to no longer require a password. If you know the tweak, do you have the right to use it? Well, you probably wouldn’t, but let’s say the bank’s policies on this matter were a little lax. Does the bank have to host tutorials on the card tweak? Absolutely not. The bank wants you to use the ATM with a password and supports that method of security.

Likewise, we on the forums support Ubuntu’s security model. If people are able to set up Ubuntu in other ways and still be secure, they can find ways to do that without the forum providing those ways.
