[ncl-talk] Question concerning listing files

[Barry Lynn]

Dennis:

This was confusing because the subdirectory with the files has a date in
its subdirectory name, and the files themselves have a date (but of
slightly different format).

If I need to sub-divide the individual files according to date than I will
need to follow your instructions.

It is unclear to me why ls has Quotes around it since it seems to be a
command, while the "nam*grb*" has Quotes around it as well (but is a
filename).
