Your question nicely illustrates the extreme need to read while using Open Source software. It just won't hold your hand like a Mac or Windows machine!
But, the rewards and the learning experience are well worthwhile.
I don't use Fedora or Red Hat, but I do use command line tools in every OS I use. Since it's better to learn why something works than just to learn a formula, I'm going to suggest a few pages to look over.
But first, the lazy way out. You said,
I tried the Command "yum install flash-plug-in"
Right away I can see a problem. It's "flash-plugin
", not plug-in
. One of the things I've found while using Open Source is that it has forced me to greatly increase observational skills. Using Windows and Mac computers tends to produce lazy users. But enough preaching.
A quick Google search
(you did try searching, right?!
) pulled these pages up.
The always-important man page
And a Fedora wiki guide
on managing software.
Enjoy the reading, have fun, and good luck!
