==A note about root privileges== Many of the commands used to compile, install or check for software packages require 'root' privileges. There are commonly 3 ways to gain such permissions. # Log in as root # Elevate yourself to root # Use root privileges for a single command * First is done by, obviously, logging in as and being root. This is the least desireable method. It's possible to - inadvertently - really screw up your system. If you were to say, run ''rpm -fr *'' you'd delete everything in the current directory and below - with no recourse or recovery. Do this in your root '/' or '/bin' directory and you've just destroyed your installed system. It also opens up an opportunity (even if slight) for evil-hacker-doods to use your root access for their own nefarious purposes. * Second is by using the ''su'' command. First you log into your system as a user, then execute 'su' to elevate yourself to root. This is basically the same as logging in as root - but when you're done doing 'root things', you can type ''exit'' and return to a normal user. It's considered a 'bit' safer, but those with an opinion say it's not much better. * Third is by using 'sudo' (see ''man sudo'' for details). This takes a bit of configuration. First you need to add your user to the 'wheel' group (edit /etc/groups) and edit the file /etc/sudoers. Once this is done, you can be logged in as a regular user and give 'sudo' as a prefix to any command. That command will be executed with root privileges and when it's done, you're immediately returned to 'normal' user status. Advantage of this is you don't have to 'exit' to get back to a normal user. But, you do have to add it to every command you want to run with root privileges.<br> For example, you can run: <br> ''sudo rm -fr /''<br> And achieve the same level of system destruction as in the first method. '''DO NOT DO THIS!''' Using sudo is the method suggested by most. In fact, on many modern distributions - it's the only way to do it as they essentially '''hide''' the root user.<br> ''Like so many things FOSS and Linux - what you use is up to you. It's your choice. One of the beauty's of FOSS is you HAVE a choice!'' For this "HowTo", I'll assume you have sudo configured. Configuring sudo is a bit beyond what I've planned here.<br> If you don't have it ready, you can just use: su - Followed by your root password and voila - you're running as root, with root's environment (that's what the - does). When you're done doing "root things", don't forget to type 'exit' and return to normal user status! For the combined CLI commands below - just break them up into individual commands. And yes - doing normal user type things as root really is a bad idea.
