I need a pause on a shell script to show a warning before continuing.
For instance, on DOS it goes like this:

doit.bat:

[...]

echo 'Are you sure? Press Ctrl-C to abort, enter to continue.'

pause

[...]

How can I do this on bash?
For the moment a sleep command seems to do the trick and is simple enough but is not exactly the idea:

doit.sh

[...]

echo 'Are you sure? Press Ctrl-C to abort.'

sleep 3

[...]

something along the lines of

echo -n "prompt"  #'-n' means do not add 

 to end of string

read              # No arg means dump next line of input
