If so, is there such a > patch exist? Since your output differs from mine, the manpages are getting damaged before they reach /usr/bin/less. Have you maybe installed your own copy of GNU groff? The original source enables ANSI escapes in manpages, but the version in FreeBSD disables them. Make sure your /usr/share/tmac/troffrc matches the content at http://svn.freebsd.org/viewvc/base/stable/8/contrib/groff/tmac/troffrc?view=markup , especially the last 10 lines or so, and check for other installations of groff. -- Dan Nelson dnelson@allantgroup.com
