As for using vim-x11, some prefer vi/vim and others emacs. It is a matter of preference. Just use what you are comfortable with.

you will need to set the script's execute permission

Code:

chmod u+x script.sh

and then you can run it by

Code:

./script.sh

You can also run it by using

Code:

bash script.sh

Assuming you are running bash, if not you would change this to the appropriate shell.

Any plain text editor is fine for shell scripting. After you save the script just set the executable bit and call it directly from the terminal.

Code:

$ chmod 'u+x' your-script

$ ./your-script

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:

Code:

bash filename.sh

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.:

Code:

#!/bin/bash

Then, if you make your file executable, you can just run it (and it will invoke bash automatically, e.g.:

Code:

$ 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 I believe that 13 is a bit out of date.

Thank you all.!
$ bash hello.sh worked perfectly. That was my first script.:-)

If you just want to test your script without making it executable just give the command

Code:

source script name

do this command from within the directory the script is located.

Open Terminal or Konsole or whatever, it depends on what distro and what DE you're using, run the command;

Code:

man bash

Manual pages are lovely, they go by;

Code:

man whatever

Have a look here too; http://ss64.com/bash/

That's for start.

Then check these 2 links, in that order (second one is something btmiller suggested);
