This might be a good start:
Create a file called myscript.sh with the following:
#!/usr/bin/sh // or what ever shelll is on Zaurus
then your commands below this
.....
give file executable privledges
chmod 755 myscript.sh
But the problem with your script is that those actions can only be done as root. You can store it in any directory you want, \"/home/zaurus\" would be a good one. since this is the directory you land in when a terminal window is fired up.
Mabye in the script you could have a \"su\" before your commands, since the root user has not password.
Sorry I can\'t offer more help. I hate scripts and try to do as little of them as I can.
