Syntax error: "(" unexpected.

[esther]

Code

main() {
    extern wakeup();
    signal(SIGNALARM, wakeup);
    while (1); {
        alarm(5);
        pause();
    }
}

Mistake

./script.sh: 3: ./script.sh: Syntax error: "(" unexpected (expecting "}")

Try this:

#!/bin/bash
main() {
extern wakeup\(\);
signal\(SIGNALARM, wakeup\);
while [ 1 ]; do
alarm\(5\);
pause\(\);
done
}
main

I'm the only one who's making mistakes on the team that I don't have in the system, but you may have: pause (may be replaced by sleep ? extern♪ signal and alarmThere's no other idea.
