Bug ID: 288089
Summary: mandoc has a lot of undocumented command line options
Product: Base System
Version: 15.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
I called the usage output:
/usr/bin/mandoc -?
mandoc: illegal option -- ?
usage: mandoc [-ac] [-I os=name] [-K encoding] [-mdoc | -man] [-O options]
[-T output] [-W level] [file ...]
so the valid command line options are -a, -c, -I, -K, -m, -O, -T, -W
I called -h and expected a help message, but mandoc hangs and waiting for input
on stdin:
/usr/bin/mandoc -h
^D
mandoc is hard linked to apropos:
ls -li /usr/bin/mandoc /usr/bin/apropos
223004 -r-xr-xr-x 4 root wheel 526456 Jul 7 07:32 /usr/bin/apropos
223004 -r-xr-xr-x 4 root wheel 526456 Jul 7 07:32 /usr/bin/mandoc
I called apropos -h and it worked as expected:
/usr/bin/apropos -h
usage: apropos [-afk] [-C file] [-M path] [-m path] [-O outkey] [-S arch]
[-s section] expression ...
same for makewhatis:
/usr/bin/makewhatis -h
makewhatis: illegal option -- h
usage: makewhatis [-aDnpQ] [-C file] [-Tutf8]
makewhatis [-aDnpQ] [-Tutf8] dir ...
makewhatis [-DnpQ] [-Tutf8] -d dir [file ...]
makewhatis [-Dnp] -u dir [file ...]
makewhatis [-Q] -t file ...
PS: the problems seems to be the getopt() call in contrib/mandoc/main.c
while ((c = getopt(argc, argv, "aC:cfhI:iK:klM:m:O:S:s:T:VW:w")) != -1) {
which contains much more than the supported -a, -c, -I, -K, -m, -O, -T, -W
options.
