Sounds fine to me :-). You might try running vim just in the terminal so you can get used to non-graphical applications. You might also want to look at some of the bash guides at www.tldp.org
to get some basic ideas about shell scripting.
You save your script as a text file, and you can run it by:
assuming filename.sh is the name of the file with your script. However, there's an easier way too. You can add what's called a shebang to the top of your script, e.g.:
Then, if you make your file executable, you can just run it (and it will invoke bash automatically, e.g.:
$ vi filename.sh # create the script
$ chmod +x filename.sh # make it executable!
$ ./filename.sh # run it
BTW, the dollar signs in the above are supposed to represent the shell prompt; you don't type them in. Good luck and happy scripting!
BTW, you might consider upgrading your Fedora at some point. I believe that 13 is a bit out of date.
