Catch SIGINT in bash, handle AND ignore

Question

Is it possible in bash to intercept a SIGINT, do something, and then ignore it (keep bash running).

I know that I can ignore the SIGINT with

trap \'\         


        

Answer 1

trap will return from the handler, but after the command called when the handler was invoked.

So the solution is a little clumsy but I think it does what is required. trap handler INT also will work.

trap 'echo "Be patient"' INT

for ((n=20; n; n--))
do
    sleep 1
done
