    So i know i can inside my script do

    methoda &
    methodb &
    methodc &

    But i want to wait until all 3 are done so that i can then check logs etc. I want to achieve this without losing the efficiency that threading provides.

    How do i check that the calls are done without stopping and waiting in each case?

    You can call the wait command to wait on spawned sub processes.

    This would be correct. Simply append the end of the script with 'wait' minus the '' of course.
