Naming convention of bash script filenames

[Peng Yu]

Hi,

I think that that may not be a unique naming convention for bash
script filenames. But I use the following.

For an executable bash script I use the suffix .sh. For a bash script
that is only source-able but runnable, I use the suffix .bashrc.

People may use different conventions. I just want to see what most
people use and follow the common practice. Could anybody give me any
suggestions?
