Code:
echo -n "Press key:"
stty -echo raw
c=$(dd bs=1 count=1 2>/dev/null )
stty echo -raw
echo " key:$c"

It interpreters ctrl-c and ctrl-d literally... Is there a way to make it to be aborted by a signal?

explain_getchar_or_die(3)				     Library Functions Manual					 explain_getchar_or_die(3)

NAME
explain_getchar_or_die - input of characters and report errors SYNOPSIS
#include <libexplain/getchar.h> void explain_getchar_or_die(void); DESCRIPTION
The explain_getchar_or_die function is used to call the getchar(3) system call. On failure an explanation will be printed to stderr, obtained from explain_getchar(3), and then the process terminates by calling exit(EXIT_FAILURE). This function is intended to be used in a fashion similar to the following example: int c = explain_getchar_or_die(); Returns: This function only returns on success. On failure, prints an explanation and exits. SEE ALSO
getchar(3) input of characters explain_getchar(3) explain getchar(3) errors exit(2) terminate the calling process COPYRIGHT
