Debian $PATH variable change
This is set in the /etc/login.defs on debian 6.0 .
These are the lines you have to edit:
# *REQUIRED* The default PATH settings, for superuser and normal users.## (they are minimal, add the rest in the shell startup files)ENV_SUPATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/binENV_PATH PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/gamesEDIT:
I forgot to put where I found the solution: https://serverfault.com/questions/166383/how-set-path-for-all-users-in-debian
Modify /etc/environment to include a line like this:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
If you are using a graphical display manager / GUI (a.k.a not just a shell or terminal) changing the /etc/profile, ~/.bashrc or other file will not change the PATH variable.
In this case you have to create the file: ~/.xsessionrc file and add something like this:
export PATH="$PATH:/sbin"(depending on the path you want to add)

NOTE for Debian 10, check out this solution first if you get command not found:
su - root instead of su root
