$ fgrep "$(cygcheck -f /usr/bin/find | sed 's/\r$//').tar." \
/etc/setup/installed.db | cut -d' ' -f1
findutils
OR
$ fgrep "$(cygcheck -f /usr/bin/find | d2u).tar." \
/etc/setup/installed.db | cut -d' ' -f1
findutils
cygcheck -f outputs DOS lines with \r which need stripped as
shown, using sed (Base), d2u, or your choice of available tool.
