While it's being talked about; 'su', then root password, gets us root privileges.
I've read on the Forum to not use sudo, so I don't, and have no need to.
From the link: https://wiki.archlinux.org/index.php/SudoRationale
Sudo is an alternative to su for running commands as root. Unlike su, which launches a root shell that allows all further commands root access, sudo instead grants temporary privilege escalation to a single command. By enabling root privileges only when needed, sudo usage reduces the likelyhood that a typo or a bug in an invoked command will ruin the system. Sudo can also be used to run commands as other users; additionally, sudo logs all commands and failed access attempts for security auditing.
The link goes into a lot of detail of how to use 'sudo'
I'm really not a command line type guy, unless I have to be, which is generally a lot of fun.
I have installed Avast!4linux workstations, a .rpm package from a totally obtuse source; an Windows Anti-Virus Company, -- only using su.
I don't really understand the danger of sudo usage, but I'll look online for a clear answer out of interest. Or maybe best I don't know what the danger is.
Actually that's not good is it, best to know the danger.
It's not about not using sudo. It's about responsible use. Even if you are the only user on your machine and you use sudo, setting it up correctly will help you understand that it's purpose is not to conveniently give root privileges to users.
OK, that's enough info actually. I get it, takes a bit of time for the penny to drop sometimes. EDIT: Old-Polack has a sticky clearly explaining the issue here:http://www.pclinuxos.com/forum/index.php/topic,90479.0.html
