manpath怎么改？（新手问题）

coldcoffee

我现在的manpath是/usr/kerberos/man:/usr/local/share/man:/usr/share/man/zh_CN.GBK:/usr/share/man/zh_CN.GB2312:/usr/share/man:/usr/X11R6/man
我不想要zh_CN.GBK和zh_CN.GB2312这两个目录，应该怎么去掉，我看了/etc/man.conf里面没有这两个path，那现在应该去那里改呢？
我的man.conf如下：

#
# Generated automatically from man.conf.in by the
# configure script.
#
# man.conf from man-1.5k
#
# For more information about this file, see the man pages man(1)
# and man.conf(5).
#
# This file is read by man to configure the default manpath (also used
# when MANPATH contains an empty substring), to find out where the cat
# pages corresponding to given man pages should be stored,
# and to map each PATH element to a manpath element.
# It may also record the pathname of the man binary. [This is unused.]
# The format is:
#
# MANBIN                pathname
# MANPATH               manpath_element [corresponding_catdir]
# MANPATH_MAP           path_element    manpath_element
#
# If no catdir is given, it is assumed to be equal to the mandir
# (so that this dir has both man1 etc. and cat1 etc. subdirs).
# This is the traditional Unix setup.
# Certain versions of the FSSTND recommend putting formatted versions
# of /usr/.../man/manx/page.x into /var/catman/.../catx/page.x.
# The keyword FSSTND will cause this behaviour.
# Certain versions of the FHS recommend putting formatted versions of
# /usr/.../share/man/[locale/]manx/page.x into
# /var/cache/man/.../[locale/]catx/page.x.
# The keyword FHS will cause this behaviour (and overrides FSSTND).
# Explicitly given catdirs override.
#
# FSSTND
FHS
#
# This file is also read by man in order to find how to call nroff, less, etc.,
# and to determine the correspondence between extensions and decompressors.
#
# MANBIN                /usr/local/bin/man
#
# Every automatically generated MANPATH includes these fields
#
MANPATH /usr/share/man
MANPATH /usr/man
MANPATH /usr/local/share/man
MANPATH /usr/local/man
MANPATH /usr/X11R6/man
#
# Uncomment if you want to include one of these by default
#
#MANPATH /opt/teTeX/man
#MANPATH /usr/lib/perl5/man
#MANPATH /usr/share/perl5/man
#MANPATH /usr/share/tcl-8.0/man
#MANPATH /usr/share/tk-8.0/man
#MANPATH /usr/share/tix-4.1/man
#MANPATH /usr/share/coas/man
#MANPATH /usr/kerberos/man
#
# Set up PATH to MANPATH mapping
#
# If people ask for "man foo" and have "/dir/bin/foo" in their PATH
# and the docs are found in "/dir/man", then no mapping is required.
#
# The below mappings are superfluous when the right hand side is
# in the mandatory manpath already, but will keep man from statting
# lots of other nearby files and directories.
