Inter-process Communication

Starting a new process or a sub process is trivial in shell. The design of gobash enables easy sharing of objects and process communication. An object can be used in a sub shell or it can be passed to a different process. We illustrate the former case below.

#!/bin/bash
. gobash/gobash

ai=$(AtomicInt 0)
( $ai inc ) &
( $ai inc ) &
( $ai inc ) &
wait
$ai val

In this example, we create an object (AtomicInt) that is used in three sub shells. Once all sub shells finish their work, we print the final value.
