First create a directory to hold your scripts:
Code:
mkdir -p $HOME/bin

Add this directory to your PATH variable if it is not already there:

Code:
case :$PATH: in
     *:$HOME/bin:*) ;;
     *) PATH=${PATH%:}:$HOME/bin ;;
esac

Choose a text editor.
Use whichever editor you fell most comfortable with. Any UNIX system will have several to choose from. My preference is emacs, but if you haven't used a text editor before, you might be better off with pico or nano.
Invoke the editor with the name of your script file, e.g.:
Code:
nano $HOME/bin/myscript

Write your script. For example:
Code:
echo "Hello, World!"

Save the file.

Exit the editor.

Give the file execute permissions with:
Code:
chmod +x $HOME/bin/myscript

Execute the script ($ is your cxommand prompt; Hello, World! is the output of the script).:
Code:
$ myscript
Hello, World!

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service	runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
       working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script.  service passes COMMAND and OPTIONS to the init script unmodified.  All scripts should support at least the start and stop
       commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start  com-
       mand.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
