I want to write a command line utility that can be used to synchronize the execution off programs in different consoles.
Console A: 
$ first_program && semaphore -signal
Console B:
$ semaphore -wait && second_program
The first program takes a long take to complete. The second program can only start when the first program has finished.
Which synchronization object do I need to implement this?
