How to create a concurrency test in a shell script?

I am trying to replicate the concurrency test in a shell script, either using netcat or whichever tool you suggest.

This is the test that I am trying to replicate:

internal/test_ping_pong.go

main


      
          			return err
          		}
          	}
          
          	logger.Debugf("Success, closing connection...")
          	client.Close()
          
          	return nil
          }
          
          func testPingPongConcurrent(stageHarness *test_case_harness.TestCaseHarness) error {
          	b := redis_executable.NewRedisExecutable(stageHarness)
          	if err := b.Run(); err != nil {
          		return err
          	}
          
          	logger := stageHarness.Logger
          	client1, err := instrumented_resp_connection.NewFromAddr(logger, "localhost:6379", "client-1")
          	if err != nil {
          		return err
          	}

So, the test starts a few Redis clients and uses them in parallel, at the same time. But, they don’t close a connection automatically after sending a command from a client. They manually close the connections (sockets/streams) at the end, but they keep the connection alive for the whole duration of the test. If I use nc it will close the connection after sending a single command, so I can’t use it for a concurrency test, at least not in the default way.

Does somebody have an idea how to make this work?
