Archive-name: finder
Ever wonder if anyone else on the system has implemented that software
package? Ever wonder where the subdirectories relevant to something
are?
Finder is a quick way to answer these questions, without doing a full
find on the system and without being limited to the directories that
whereis looks at. Finder itself, however, is limited to a search on
directory names.

The finder package is implemented as /bin/sh scripts using find and
awk. You may want to customize the find command in mkfindex -- for
example, not to cross mount points (-xdev, if you have it). Perl would
probably do the job even faster than awk and if anyone translates this,
I'd like a a copy.
To get an idea of how big the index files (.findex) are, the one at the
root of our system covering 2.8 gigabytes of disk space in use is about
145 kilobytes.
