查看bdf的用法：
fabdb1$[/home/oracle]man bdf
bdf(1M) bdf(1M) ## bdf ##
NAME
bdf - report number of free disk blocks (Berkeley version) #报告磁盘的剩余空间块
SYNOPSIS #简介
/usr/bin/bdf [-b] [-i] [-l] [-s] [-t type | [filesystem|file] ... ] bdf [-b] [-i] [-l] [-s] [-t type | [filesystem | file]… ]
DESCRIPTION #描述
The bdf command displays the amount of free disk space available bdf命令展示了在指定的文件系统中可以使用的磁盘空间大小，如果
either on the specified filesystem (/dev/dsk/c0d0s0,for example) or 没有文件系统被指定，则打印所有正常安装的文件系统的可以利用的
on the file system in which the specified file (such as $HOME),is 空间，打印的单位是kilobytes(千比特，kb)
contained. If no file system is specified,the free space on all of 注意：1Gb=1000 000kb
the normally mounted file systems is printed. The reported numbers
are in kilobytes.
Options #选项
The bdf command recognizes the following options: bdf命令有以下选项：
-b Display information regarding file system -b 展示有关文件系统交换信息
swapping.
-i Report the number of used and free inodes. -i 展示可利用的空闲空间的大小
-l Display information for local file systems only -l 仅仅展示本地文件系统的信息
(for example,HFS and CDFS file systems).
-s Do not sync the file system data on the disk -s 在报告使用前不同步文件系统的数据，注意得到的数据可能
before reporting the usage. Note that the data 不是最新的
reported by bdf may not be up to date.
-t type Report on the file systems of a given type (for
example,nfs or hfs).
RETURN VALUE #返回值
The bdf command returns 0 on success (able to get status on all file 成功返回0，失败返回1
systems),or returns 1 on failure (unable to get status on one or more
file systems).
WARNINGS #警告
If file system names are too long,the output for a given entry is 如果文件系统名字太长，将分成2行输出展示。
displayed on two lines. bdf命令不会计算磁盘保留用于交换的空间…
The bdf command does not account for any disk space reserved for swap 小结：bdf命令与其它查看空间的命令在计算空间的方法上有所区别，
space,or used for the HFS boot block (8 KB,1 per file system),HFS 命令得到的结果也会有一些出入。
superblocks (8 KB each,1 per disk cylinder),HFS cylinder group
blocks (1 KB - 8 KB each,1 per cylinder group),and inodes (currently
128 bytes reserved for each inode). Non-HFS file systems may have
other items not accounted for by this command.
