I have a unimrcp client process (ucp) and I want to spawn multiple ucp using shell script.

Whenever I spawn a ucp, it returns a command line using which I can access different functionalities in ucp. So I want to write a script that achieves following,

1. Spawn a ucp process


2. wait until the ucp's command line appears


3. access ucp's functionality with a command "run recog"

Note that ./ucp && run recog does not work since ./ucp is finished only after we exit from the command line of ucp.

I tried the following for this,

#!/bin/bash 
./ucp & 
fg 
echo "run recog uni2" 
wait 

However, ./ucp & results into starting the client process and then writing "?????" on the client console resulting into "????" command not found. Following are the logs,

./script.sh

unknown command: ??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

Is this the right way to achieve what I mentioned in the question? (spawn a client and run a command on its console)? If yes, why does the "./ucp &" results in reading "?????" considering that as input to its console? Note that this does not happen if I simply fire "./ucp & fg " from the console. It can see the expected behavior of the command when I do it from the console. The issue appears when I try to execute the script.

If this is not a right way, How can I achieve what I mentioned in the question? (1, 2, and 3)

Thank you
