一些技巧

用who -l 可以察看日志文件 / var/log/wtmp

named_program="/usr/local/sbin/named"
named_flags="-c /etc/namedb/named.conf"
tar czvf - /usr/home/vpopmail > /bak/mail-bak/mail-db/2005-9-17.tgz
tar czvf - /www/virtualhosts > /bak/virtualhosts-bak/virtualhosts-zl/2005-9-17.tgz

tar czvf - /usr/home/chb2 > /bak
tar zxvf myTGZfile.tgz -C /usr/local(解压倒指定目录)
/usr/local/share/mysql/mysql.server stop
chown mysql:mysql /var/db/mysql
sockstat -4
把/var/db/mysql 整个删除
然后运行mysql_install_db

You can get a good standard workstation install by using the
instant-workstation port/package.  If you have ports installed, you can
install it by doing
        # cd /usr/ports/misc/instant-workstation
        # make install && make clean
as root.  This will install a collection of packages that is convenient to
have on a workstation.
You may also use sysinstall(8) to re-enter the installation and
configuration utility.  Edit /etc/motd to change this login announcement.
You can get a good generic server install by using the
instant-server port/package.  If you have ports installed, you can
install it by doing
        # cd /usr/ports/misc/instant-server
        # make install && make clean

du -d1 -h /var  显示本目录内所有子目录大小（K/M）
