you're right.
i was pursuing parallelism with glob("*"), that's all.
glob("string*ext")
would translate into
grep /string.*ext/
for example.

DEBIAN NEWBIE TIP #3 from Will Trillich <[EMAIL PROTECTED]>:
Wondering how to find WHICH PACKAGE CONTAINS x-y-or-z? Just enter
"dpkg -S part/of/path" and you'll get a list of all packages that
affect paths like that. For an example, try "dpkg -S http".
