hi,


for building menus you can use "select"

man bash

then look for select (select is a bash built-in)


for controlling signals you can use "trap"

man trap

NOTE - there are some signals you can not trap

[Please]

HI Thanks for your advice but I did not get ideal.

If you can ,please help me

We haven't seen your script yet.

Surely you didn't expect us to write the script for you? That won't help in the long run. You need to scroogle the following search terms:

We're not impolite, just busy writing our own scripts. :) When you have a script, and it doesn't work, and you have a specific question about why it doesn't work, we'd be glad to help.

It looks like you've done everything except actually fill in the individual items.

The next step is to do these things at the command line:

man nslookup
man ping
man 8 shutdown

Then do the "trap dance", as previously suggested, and you're there.
