HP Unix bdf显示不在同一行,一行记录分成两行显示

[root->/]# bdf
Filesystem          kbytes    used   avail %used Mounted on
/dev/vg00/lvol4    35848192 27096088 8683928   76% /
/dev/vg00/lvol1    1835008  636952 1188752   35% /stand
/dev/vg00/lvxxxx02
                   20971520   71784 19593510    0% /xxxx02
/dev/vg00/lvarc
                   10485760   20062 9811599    0% /arc
/dev/vg00/lvoracle
                   20971520 17393817 3354134   84% /oracle


使用df -P 使数据现在在同一行，但是显示单位不太一样，导致和bdf结果不太一样。baidu一下   
[root->/]# df -P
Filesystem             512-blocks  Used  Available Capacity Mounted on
/dev/vg00/lvoracle 41495904 34787662  6708242    84%     /oracle
/dev/vg00/lvarc 19663322    40124 19623198     1%     /arc
/dev/vg00/lvxxxx 39330588   143568 39187020     1%     /xxxx
/dev/vg00/lvol1       3651408  1273904  2377504    35%     /stand
/dev/vg00/lvol4       71560032 54192128 17367904    76%     /


加上k参数，df -kP,结果和bdf比较接近，还有有些数据差入
[root->/]# df -kP
Filesystem            1024-blocks  Used  Available Capacity Mounted on
/dev/vg00/lvol4       35780016 27096120  8683896    76%     /
/dev/vg00/lvol1       1825704   636952  1188752    35%     /stand
/dev/vg00/lvoracle  20747973 17394179  3353794    84%     /oracle
/dev/vg00/lvarc  9831661    20062  9811599     1%     /arc
/dev/vg00/lvxxxx  19665294    71784 19593510     1%     /xxxx


摘录网上的信息:
Hp-UX中bdf和df的区别
HP-UX measures space in 1024-byte blocks in bdf, but 512-byte blocks in df. 
The df command is a standard UNIX report of free disc space. 
bdf is a nicer Berkeley form of df supplied with HP-UX; 
it shows free and used disc space on each file system (it does not include Swap Space and other overhead disc space).  
Here is some sample bdf output:
 
Filesystem kbytes used avail capacity mounted on
/dev/vg00/lvol1 104097 66657 27030 71% /
/dev/vg00/lvol5 79449 21 71483 0% /tmp
/dev/vg00/lvol4 99385 64732 24714 72% /users
/dev/vg00/lvol3 496865 418420 28758 94% /usr
dumbo.robelle.com:/sys/apps 627120 455712 171408 73% /pcserver/sys/apps
/dev/dsk/c3d0s2 546660 546660 0 100% /cdrom1
/dev/dsk/c4d0s2 321402 321402 0 100% /cdrom2 


The /vg00 file systems are logical subdivisions of the hard drive allocated to different subdirectories under the root directory. 
The idea is similar to account and group limits in MPE. 
The dumbo file system is a LAN PC server, mounted as a Network File System on UNIX. 
And the last two are CD-ROM drives with the HP-UX and MPE manuals mounted. 
The capacity column is sort of equivalent to MPE/iX's max Perm percent, in that 100 percent doesn't mean that the disc is full. 
HP-UX generally makes the disc look 100 percent full when it is actually about 90 percent full. 
The remaining 10 percent is given only to superuser.


bdf reports kilobytes free per HP-UX file system. 
See /etc/checklist/ for all file systems known to your HP-UX system and /etc/mnttab/ for all file systems which are mounted. 
Disc space is managed as "device-files"; see /dev/dsk/* for all disc devices. 
When you run out of disc space, the error you see is "No space left on device." 
To find out who is using the disc space on HP-UX, try du -s /users/*. 
This shows how many 512-byte blocks are used by each subdirectory under /users.
