1) Recommend that you do not call a script or a function "init". It is the name of the fundamental unix program which runs at the top of the process tree.
2) As posted the script does nothing. It is just a function and there is no code to call the function. There is also no code to put a value into "$ls" should someone call the function.
What did you type on the command line?
What is actually in the script?
