I wanted to know why SU is to be used over Sudo in this Distro, I understand that they are about the same thing anyway but some things require you to be in the Sudoers list, just dumb things like Dolphin when adding ROOT menu links and stuff like that. There may be other ways to do these things but I haven't found how.

I also don't understand why all distro's make being in the sudoers list a manual step, most that mess with TUX are able to easily add them self's yes but why add the extra step?

Just a question is all, not looking to change the wheel. I just was curious if there was a reason for both

Thanks for the info I have been using Sabayon for along time and never knew that su - was preferred. I have used sudo command for most things without issue. It makes sense that the path would be different though.

su

or

su -

?

I use su -

su and su - are not quite the same thing. If you use 'su -' it's like logging in directly as root user from a VT. From the man page for su command:

-, -l, --login
Provide an environment similar to what the user would expect had the user logged in directly.

When - is used, it must be specified as the last su option. The other forms (-l and --login) do not have this restriction.

Code: Select all: fitzcarraldo@meshedgedx ~ $ su Password: meshedgedx fitzcarraldo # echo $SHELL /bin/bash meshedgedx fitzcarraldo # whoami root meshedgedx fitzcarraldo # echo $PATH /sbin:/bin:/usr/sbin:/usr/bin meshedgedx fitzcarraldo # cd ~ meshedgedx ~ # pwd /root meshedgedx ~ # exit exit fitzcarraldo@meshedgedx ~ $

Code: Select all: fitzcarraldo@meshedgedx ~ $ su - Password: meshedgedx ~ # echo $SHELL /bin/bash meshedgedx ~ # whoami root meshedgedx ~ # echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.6.3 meshedgedx ~ # cd ~ meshedgedx ~ # pwd /root meshedgedx ~ # exit logout fitzcarraldo@meshedgedx ~ $

Compare the environments for the two:

Either 'su -' or 'su' should be fine with Gentoo and SL. I use su and have never had any problems.
