I know I've seen something about this before: When I use -execdir, I get a message like:
find: '/usr/share/texlive/texmf-dist/tex4ht/ht-fonts/alias/kurier/sy-iwona': Too many open files find: Failed to save working directory in order to run a command on 'qx-iwonacap': Too many open files But I can't find an entry in the bug tracker (http://savannah.gnu.org/bugs/?group=findutils) about it. (BTW, the search facilities in that tracker are really poor.) It seems that replacing -execdir with -exec makes that problem go away, but as the manual page says, there are significant security problems with -exec. Dale
