In describes it like in my man pages directly after all the options. The date on the bottom of the page says March 31, 1994. Physical dates on l */chmod in /usr/share man look like this -rw-r--r-- 1 man wheel 2817 Sep 4 10:33 /usr/share/man/cat1/chmod.1.gz -rw-r--r-- 3 man wheel 2426 Mar 20 2000 /usr/share/man/cat2/chmod.2.gz -r--r--r-- 1 root wheel 3584 Sep 1 10:35 /usr/share/man/man1/chmod.1.gz -r--r--r-- 3 root wheel 3160 Sep 1 10:34 /usr/share/man/man2/chmod.2.gz Note that the dates relate to the time of the last makeworld and install world and is is release 4.4-RC. However if you enter chmod on a command line with no argument like this: Usage: chmod [-fhlHLPR] mode file ... Here is an -h flag there. There is no indication of a -v flag which is in the documentation. > My manpage for chmod says: > > -h If the file is a symbolic link, change the mode of the link > itself rather than the file that the link points to. And it is not in mine. My /usr/src/bin/chmod/chmod.1 also does not have an -h flag. The source - chmod.c - in that diretory say this. ------------- case 'h': /* * In System V (and probably POSIX.2) the -h option * causes chmod to change the mode of the symbolic * link. 4.4BSD's symbolic links don't have modes, * so it's an undocumented noop. Do syntax checking, * though. */ hflag = 1; break; /* -------------- > It would help if you mentioned which version of FreeBSD you're > running, and when the chmod manpage you have was last updated.

While I am not the author of the original comment I did the above, quoted the man pages, showed the source of the man pages, and the above source code has a date of August 16 09:36. I perform cvsup regularly. Now let me ask the same question you ask of the original poster. Dates of your man, man sources, chmod.c and chmod.1 ? It would interesting to see where the divergance occurs.
