Need help with shell script

tomarkblake · 05-29-2005, 12:29 AM

I know this is a big ask, but I need to write a shell script that acts as a menu system. It needs to

1/ Clear the screen
2/ Print out a menu list with a number at the front of each menu item
3/ Wait for a selection by printing a prompt

The menu tasks are

1/ Show the path environment variable
2/ Display the home directory usage for a user
3/ List all users on the system
4/ Exit

Scripts are certainly not my strong point, so if anyone can point me to a resource that can teach me how to achieve the above, I would be very greatful.

Thanks in advance,
Mark

No problems

its hard at first but when you learn it you will find that you could do a script that does anything that you want , and you will soon discover the power of scripting and linux

yw

but watch out for my broken code: `echo' followed by `clear' is rather lame, so kids: don't do that at home
