Functions | Returning value from called function in a shell script

The functions computes a value, function returns a single value at a time.

Functions are used to develop an modularity, A large program can be split into multiple small modules. Each module performs an specific task. Instead of writing the code over and over again we can write single function and call the function whenever you want and wherever you want throughout the program.

When a bash function ends its return value is its status: zero for success, non-zero for failure.
