Hi, Aia.

Yes, I noted that. His title was What is the meaning the $ special character?

He also asked ...explain to me how it's categorized and it's extract [sic] definition?

He did not restrict the meaning to any special instance.

I appreciate that he used Google, but I think he may not have had enough time to internalize the information. I know that I don't always understand something just after I read it.

For example from the Wikipedia article: In most shell scripting languages, $ is used for interpolating environment variables, special variables ... -- it seems hard to imagine an alternate definition.

Thanks for the comment, it's always useful to have feedback and more than one set of dispassionate eyes looking over things ... cheers, drl
