sudo without entering a password!

Hate entering password every time you have to do some administration work? Do this. Not a secure thing. I do this because nobody else uses my computer.

sudo vsudo

Move cursor to the following line:

%admin ALL=(ALL) ALL

Change it to %admin ALL=NOPASSWD: ALL

Press Ctrl+X

Type Y to save

Press ENTER to confirm the file name.

That's all! Now you will not be asked for your password when you sudo.
