Hi,
Here is a patch which will cause locate to read every database only
once. This will cause a functional change: When using multiple
databases /and/ multiple patterns, the order in which results are
output changes from {d1p1, d2p1, d1p2, d2p2} to {d1p1, d1p2, d2p1,
d2p2}. Also, --statistics can be combined with patterns to get
statistics on the matches, and --print (-p) can be used to output names
when they otherwise would not (because of -S/-c).
Inline is a version of the patch ignoring whitespace-changes, for easy
review. The attached version includes the whitespace-changes, and is
intended to be applied.
A possible ChangeLog-entry:
2005-05-29 Bas van Gompel <[EMAIL PROTECTED]>
* doc/find.texi: Add documentation for locate --print (-p), and the
use of non-options with --statistics.
* locate/locate.1: ditto.
* locate/locate.c: Read each database only once.
Add a ``--print'' (``-p'') option. (to cancel side-effects of -c/-S)
Allow ``--statistics'' in combination with non-options.
