Shell Programming and Scripting

Hi all,

I am trying to end a Menu script. Can people suggest various methods please?

At the moment I am doing:

Code:

quit=n
while [ "$quit" = "n" ]
do
...Code
Code
Code...
read userinput
case $userinput in
q|Q) quit=y;;
esac
done

But this doesn't seem to work every time, occasionally it will work, but sometimes I will have to enter q twice.

Looks okay to me, thonly thing I might suggest is to try changing:

Code:

q|Q) quit=y;;

to

Code:

"q"|"Q") quit="y";;

?

Why? That makes no difference.

Something you haven't posted is also reading the standard input.

To ensure the shell knows absolutely for sure that it is comparing strings, clutching at straws I know but worth a try!

Sometimes it works fine the way it is.. just sometimes it takes me entering Q a few times before the script will actually end.

Is there a command to force end a script? Like virtually pressing Ctrl & C?

Don't post mutliple threads on same issue (you have posted another thread on "virtually" sending Ctrl+C). You should try to find the root cause i.e. why the script needs multiple input instead of funny workarounds like sending interrupt signals.

Post the entire while loop in CODE tags. As CFAJ said, most probably something other than read is waiting for standard input.
