sudo and gksudo

[Q] What's the difference between sudo and gksudo?

[digest]
"gksu is a frontend to su and gksudo is a frontend to sudo. Their
primary purpose is to run graphical commands that need root without
the need to run an X terminal emulator and using su directly."


"gksudo puts up a graphical password prompt, and won't mess up GUI logons when used to run graphical apps.
sudo is basically just a terminal version of gksudo. It doesn't understand X apps ..."


still confused???

--> example
"Using sudo with a graphical application does not work 100% of the time if you open an app using Alt-F2 for example if you if you press Alt-F2 and type: ... "

*** try "sudo synaptic" and "gksu synaptic"


"
There's absolutely no difference in Ubuntu because...
oli@bert:~$ ls -l /usr/bin/gksudo
lrwxrwxrwx 1 root root 4 2010-09-27 18:23 /usr/bin/gksudo -> gksu
...
"
