[dgplug-users] My response to "5.Why or Why not use sudo/su ? (2 versions of responses)

[Sabniveesu Shashank]

Hi,

[
*Simple response]*
Think of what "sudo rm -R *" can do. It removes all files in your home
directory - your downloads, your documents, music & videos and all changed
settings of your daily used applications.

Think of what "sudo rm -R /" can do. Well, if you know that "/" in
GNU/Linux indicates the root of the entire disk structure, you know what
you are messing with

The danger is that if these are your second or further commands (with
sudo), you won't be prompted for password even!

[*Advanced response]*
A recent note I made after seeing a Google+ post which blew my earlier
assumptions that this power of sudo/su is only unnecessarily hyped:


Why sudo is dangerous? (I'm not answering this here)
