The recent change from historic mandoc to the newer stuff
has broken apropos(1). From the apropos(1) manpage
MANPATH The standard search path used by man(1) may be changed by
specifying a path in the MANPATH environment variable.
Invalid paths, or paths without manual databases, are
ignored. Overridden by -M. If MANPATH begins with a
colon, it is appended to the default list; if it ends with
a colon, it is prepended to the default list; or if it
contains two adjacent colons, the standard search path is
inserted between the colons. If none of these conditions
are met, it overrides the standard search path.
In my .cshrc I have
setenv MANPATH /usr/local/man:/usr/share/man:$HOME/man
% setenv | grep MANP
MANPATH=/usr/local/man:/usr/share/man:/home/kargl/man
% apropos apropos
(Warning: MANPATH environment variable set)
/usr/home/kargl/man/mandoc.db: No such file or directory
apropos, whatis(1) - search manual page databases
Historically, there is no noise. Neither the warning about
MANPATH being set nor a message about a missing .db file were
printed. This should at least be hidden behind -v.
% unsetenv MANPATH
% apropos apropos
/usr/home/kargl/man/mandoc.db: No such file or directory
/usr/local/lib/perl5/site_perl/man/mandoc.db: No such file or directory
/usr/local/lib/perl5/5.16/perl/man/mandoc.db: No such file or directory
apropos, whatis(1) - search manual page databases
Unsetting MANPATH seems to not revert to a standard manpath of
/usr/share/man (or maybe /usr/local/man:/usr/share/man). Also, why is
it suddenly picking up the perl5 directories? There is no /etc/man.conf
on the system and login.conf does not define manpath.
setenv MANPATH :$HOME/man
% apropos apropos
(Warning: MANPATH environment variable set)
/usr/home/kargl/man/mandoc.db: No such file or directory
MANPATH was not appended to the standard search path.
So, starting the exercise over with MANPATH removed from .cshrc.
Re-login-ing into the system
% setenv | grep MAN
MANPATH is not set as expected.
% apropos apropos
/usr/home/kargl/man/mandoc.db: No such file or directory
/usr/local/lib/perl5/site_perl/man/mandoc.db: No such file or directory
/usr/local/lib/perl5/5.16/perl/man/mandoc.db: No such file or directory
apropos, whatis(1) - search manual page databases
So, some default search path is followed
% setenv MANPATH :$HOME/man
% apropos apropos
(Warning: MANPATH environment variable set)
/usr/home/kargl/man/mandoc.db: No such file or directory
% man apropos
No manual entry for apropos
