OK, it took me a while to figure it all out but I've finally successfully installed Realplayer plugin, flashplayer plugin and Acrobat reader last night. I found the rpm for realplayer. I've also finally worked out how to navigate through the operating system files.
I don't understand what you mean by tabbing though, I've been writing the full path to files. I also discovered you have to use upper and lower case as it's written.
If there is an easier simpler way of doing things I would love to know!
I've also been searching for help on the internet and now have a basic command reference and basic console commands. I wanted to remove the installation directory for flashplayer but when I tried "Deleting" access was denied and when I used "rmdir" as root I was told the "directory is not empty".
Can anyone recommend a really good beginners manual which takes you right from the basics? I could really do with one.

the equivalent to deltree under linux is
rm -r -f *
(i think)
And the tabbing stuff works kinda like this
let's pretend you are at /
to change directory to /home
you will usually type
cd home
but if you type
cd h
and then press tab it will complete til it matches all of the possibilities in that directory, most likely it will complete it right and next you'll see will be
cd home/
just press enter and you're done, you just saved 3 keystrokes
Same for files, when executing just type
./ and the first character of the file, unless there are several matches in which case you will have to add extra characters and press tab again.

chcr said:I didn't know it worked for ./ as well!
Well, you live and you learn (if you're lucky).
It works for any file/path, it even works if the program is in the PATH just start typing a command and press tab it will present the list of all matches or if it is over 200 elements it'll ask you.

i'm going to just enter some things that may or may not have been cleared up already
absolute vs. relative paths
when you use a leading forward slash in a path it is interpreted from the root of the disk, if you leave it off the path is relative to your current directory, for example:
and scripts

btw ~/ is a shortcut to your home directory when used in a path, type cd w/o any arguments to go there too.
if you look at the permissions -rwxr-xr-x you see that this script is set as executable. this is generally the case. you can call executable files like so
both of these formats do the same thing. you can use ./ when the script you want to run is in your current (working) directory. calling a script using the full path allows you to run the script from any working directory. keep in mind that running a script from a different directory may cause problems, especially if the script depends on files in it's directory (that may be confusing). one more thing about scripts, they can also be called using the interpreter they are written in. for example, a script written in perl can be called with perl script.PL. bash scripts are quite common and can be called with sh script.sh. This is probably a lot more than you wanted to know but i'm really fucking bored.
