Introduction

Sudo stands for "su do", and means "do something as the supervisor". `sudo` is an enhanced alternative to the Unix `su` command which allows any user to obtain superuser privileges

Execution

Editing by hand

Simply edit /etc/group with your favorite text editor, adding a user to the wheel group.
Assuming your username is john_doe the entry for the wheel group will look as follows:

wheel:*:0:root,john_doe

Using sudo command

Adding a user to the wheel group can be achieved using the sudo command itself.

To place a user in the wheel group when her account is first created, you would run:

  # sudo useradd -G wheel john_doe

Note: The above also creates the jdoe group automatically, use the -g argument if you wish her default group to be different.

If the user already exists and you wish to add her to the wheel group, you would run

  # sudo user mod -G wheel john_doe

That's all folks. Marcin

They have a KDE version and a Qt one, which I use on Fedora 15. I must say is the best CHM Viewer I ever used.Ps: just to confirm, names in repos (At least Fedora) solhud be: - kchmviewer-qt (in case you're not in kde recommended)or- kchmviewer (you still don't need to use kde but it'll need a lot of kde dependencies, as expected) </comment>
