Sudo is used when you don't know root password but you are nevertheless authorised by the 'root' to do all his duties. This is helpful in some situations; for example say you left the organisation, its enough to remove your account. Root password need not be changed! But for su to work you need root password! It is used by superuser himself to gain root privileges if and when required when he is logged in using his normal account. > When I use the first one it says > [user] is not in the sudoers file.

This, of course, looks silly in personal computers where you typically know root password but created a new account and forgot to add that username to sudoers file. [The user created during install is in sudoers file by default] -- *அகிலன்* (Akilan R) (http://www.coding-aviator.blogspot.com) *I should have no use for a paradise in which I should be deprived of the right to prefer hell.* --Jean Rostand _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
