How to run sh from sh file

Question

I developed a Java application. I divided the application into 5 sub-applications, and created a service wrapper to each sub application using shell scripts:

subaap1/bin/app.sh
subaap2/bin/app.sh
...

Now I want to create a startup script startup.sh to execute all the wrapper scripts:

#!/bin/bash
sh subaap1/bin/app.sh start
sh subaap2/bin/app.sh start
...

But when I run it, I get:

Unexpected command: start

How can I fix this?

Answer 1

You shouldn't need to use sh in your script to run your sub applications.

Just use:

#!/bin/bash
subaap1/bin/app.sh start
subaap2/bin/app.sh start
...

Updated as per comments below:

your version should work, however you need to know what shell sh is calling. It may be that you have the wrong shell, or the permissions on your apps are incorrect for the shell you are trying to use.
