bash - Importing shell script function

Question

I have a function err() in file abc. The files do not have a .sh extension, but they start with #!/bin/bash.

err () {
    echo "${1}" >&2 
}

Now I am importing it in a different file xyz:

source abc
someFunction(){ 
    err "Failed to back up"
}

Is this the right way of importing?

Answer 1

Yes, you can do like you mentioned above or like: . FILENAME

The file need not to end with .sh
