5. Signals + Fork

Write a program repeater.c:

./repeater Number Seconds command arg1 arg2 …
It ignores SIG_INT (Ctrl+C) itself
It forks a child that constantly:
- sleeps Seconds seconds
- forks/execvps command arg1 arg2 …
- Can be terminated by SIG_INT
It waits for the child to terminate, and forks another
After a Number of children are terminated one by one, it stops

Hint: see SIG_IGN and SIG_DFL constants in signal

E. g.:

   1 $ ./repeater 5 1 echo qq
   2 qq
   3 qq
   4 ^Cqq
   5 qq
   6 ^Cqq
   7 ^C^Cqq
   8 ^C
   9 $
