Command prompt from within a script?
I am writing a menu script and one of the options is to access a Command Prompt and return to the menu via CTRL-D. I have tried using a loop and echoing the PS1 value, then using read to assign whatever is entered into a variable, then executing the value of that variable as a command using
. $variable. it would look something like this and would work just fine except for one thing.....I have no idea how to put CTRL-D into the script. If i hit the CTRL button from within the vi editor it has its own special function. I've tried ^D, and whatever else i could think of but to no avail.

clear
do until [ $variable = CTRL-D ]
echo "`PS1`:"
read variable
. $variable
esac


thank you in advance

If you read the rules and understand homework isn't allowed, why post a new question about the same problem?
