Parallel and sequencial script execution

Question

Need to run the following: if script-a ok, run script -b and script-c in parallel.

Tried the following code, but it runs script-a && script-b and script-c in parallel.

script-a && script-b & script-c & wait

Is there a way to group script-b and script-c?

Answer 1

Use braces:

script-a && { script-b & script-c & wait; }
