Oops...
Sorry for the second post - but I forgot to answer your first question.

Linux/Unix shells have a much richer set of shell expansion functions
than does DOS/Windows. In addition to:

* - expand to 1 or more characters
? - expand to exactly 1 character

you can use
[...] - expand to any one of the characters in the brackets.

i.e.,
[asdf] expands to either a, s, d, or f.
[2c] expands to either a 2 or a c.
You can also specify ranges:
[a-p1-4] expands to any letter between a and p, or any number between 1
and 4, inclusive.

So, glibc-[dp]* will expand to any name starting with glibc-d or glibc-p
(devel and profile in this case).

Kinda nifty little trick this one.
