10 Mistakes New Linux Administrators Make

“#4: Avoiding the command line
“No one wants to have to memorize a bunch of commands. And for the
most part, the GUI takes care of a vast majority of them. But there
are times when the command line is easier, faster, more secure, and
more reliable. Avoiding the command line should be considered a
cardinal sin of Linux administration. You should at least have a
solid understanding of how the command line works and a small
arsenal of commands you can use without having to RTFM. With a
small selection of command-line tools on top of the GUI tools, you
should be ready for just about anything.

“#5: Not keeping a working kernel installed Let’s face it,
you don’t need 12 kernels installed on one machine. But you
do need to update your kernel, and the update process doesn’t
delete previous kernels. What do you do? You keep at least the most
recently working kernel at all times. Let’s say you have
2.6.22 as your current working kernel and 2.6.20 as your backup. If
you update to 2.6.26 and all is working well, you can remove
2.6.20.”
