Continuing my AWK explorations I've written a query tool which lists
the N most recent e-book additions to the RTC lending library:
--
~$ ~zilog/public_bin/recent_books.awk -h
Returns the N most recently added RTC library books.
usage: recent_books.awk [ -h | N ] ; N defaults to 10
made with GNU Awk, version 5.2.2
~$ ~zilog/public_bin/recent_books.awk 7

The tool makes use of gawk-specific features, namely it's support for
shared library extensions. gawk comes with several native shared library
extensions, sort of a "demonstration kit", of which recent_books.awk makes
use of two: readdir(3am) and filefuncs(3am). The latter is particularly
useful as it provides access to a number of file/dir functions that one
would otherwise have to rely on operating system tools for. Glancing at
the man page suggests possible further refinement of recent_books.awk
such that the readdir(3am) functions can be replaced with filefunc(3am)
functionality.
