Make user sudo

# Debian - add a user to the sudo group:
su
/sbin/usermod -aG sudo username

Note, using su instead of sudo requires the full path to usermod since sbin is not in the path with this method, that is why it is there.

# in Ubuntu:
su
adduser username sudo

Note, a _full_ logout of the user must be done as /etc/sudoers seems to be edited upon login. It is not enough to make a new shell.

# in Slackware (12):

Edit /etc/sudoers, uncomment the following line:
# Uncomment to allow people in group wheel to run all commands
# %wheel  ALL=(ALL)       ALL

So it looks like this:
# Uncomment to allow people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

Save the file. Then add the user to the wheel group:
gpasswd -a username wheel

Note that usermod "-a" does not exist in Slackware 12.
