I want the work of the script below to continue after the interrupt arrives and until the first successful entry. In C usually used sigsetjmp() and siglonglmp(). Any alternatives in Shell scripts? Thanks.

i()
{
    echo "Okay ..."
}
trap 'i' INT
read -p "X " X

Do you mean that you want to restart the read if SIGINT is raised? – rici Dec 16 '17 at 03:29
Yes, I literally mean this one – Ilya Timokhin Dec 17 '17 at 14:34
When I try your script with an added `echo $X has been read.`, the `echo` is executed and prints what I entered after the interrupt, i. e. it behaves as you desire without further ado. – Armali Jan 07 '20 at 08:43
