Use fmt.Sprintf like this:

Thank you so much @lutzhorn :slight_smile: I need to return this Version value to this Nested1 function. Can you please help me with that as well :slight_smile:)

Then you should return a value from your func. Did you work through the Go Tour?

@lutzhorn yes I know how to return value to function. But I need to know how to return the shell variable to function?

What module is the function exe_command part of? I don’t find it in os/exec. Do you use some 3rd party package? Which?

The package os/exec allows you to connect to the pipes STDIN, STDOUT, and STDERR of the subcommand. Take a look at the example of func (*Cmd) StdoutPipe. This example explains who to read from STDOUT.

See (*Cmd) Output example.
