#=========================================
#!/bin/sh
installdirs= /bin /sbin /usr/bin /usr/sbin /usr/libdata /usr/libexec /usr/include
/usr/share /usr/lib
for dir in ${installdirs} ; do
find ${dir} -type f -ctime +1 -delete
find ${dir} -type d -empty -delete
find ${dir} -type l -delete
done
# 4.x -> 5.x only:
# rm -rf /kernel* /modules*
cd /usr/src && make installworld
#=========================================
The second "make installworld" is to repopulate your lib/compat/ dirs,
rebuild the hierarchy and to catch files (groff support IIRC) that
this erroneously deletes.
I do this pretty often.
