Echo output to terminal within function in BASH

Question

I am writing a script in BASH. I have a function within the script that I want to provide progress feedback to the user. Only problem is that the echo command does not print

Answer 1

Dont use command substitution to obtain the return value from the function

The return value is always available at the $? variable. You can use the variable rather than using command substitution

Test

$ function test_function {
> return_val=10; 
> echo "Echo value  to terminal $return_val";
> return $return_val; 
> }

$ test_function
Echo value  to terminal 10

$ return_value=$?

$ echo $return_value
10
