[SOLVED] Command 'su -' works but 'sudo' gives error

Finally figured it out.

Here are the steps in a bottleneck to help a fellow in need.
1) Edit /etc/sudoers with visudo and add this line.

Code:

<your-user> ALL=(ALL) <commands-you-want(with path) or ALL(for all commands)>

2) Type sudo to check if it is installed. If not, then install it.(http://linuxg.net/how-to-install-and...-slackware-14/)
3) Once installed, open /etc/profile, look for PATH and add ':/sbin' at the end before double quotes or other path if the command is in another folder and save.
4) Logout
5) Login back with the user and try 'sudo <your-command>. It should work now.

Now the only thing that is left is to remove /sbin, as in to use 'sudo poweroff'. I think adding path /sbin to $PATH should work. Right? If so, how and where do I add path?

Hi,

You can export the path as

Code:

export PATH=/sbin:$PATH

/sbin is the new path you would like to add while
$PATH has the existing paths you need to retain in the new path.

Hope this is Helpful.

I tried export but the path it had added was removed when I restarted the system. However, editing directly in the file worked.

This problem has been solved. Thanks for the input though. Much Appreciated.

After:

Code:

# User privilege specification
root    ALL=(ALL:ALL) ALL
myuser  ALL=(ALL:ALL) ALL

Or something like that.

That is the correct answer and I use to do that for a sudo user. After that for logging in, use the following command to get into root:

sudo su -

and give myuser password again!

Environment variable settings are unique to that terminal and its child processes. If you want a change to the environment variable to be applied to all future terminals then you need to add it to your .bashrc or .bash_profile file.

No it isn't and chrism01 already posted how sane folks should use Sudo (http://www.linuxquestions.org/questi...#post4975941):
