I have noticed that some of my files have an asterisk at end.

Does the asterisk at the end have any particular significance? I think they are mostly executable and displayed in green by the ls command.

You will see that ./bkmp* and ./bkmp0* have an asterisk at the end. They are executable bash scripts.

Here's my output:
