You seem to have solved this. Bill Hassell has a very nice script that handles 2-line 'bdf' output and adds lots of useful information in addition to improving the output formatting. See this thread for a copy:

Different tools often use different methods to deduce things. You are quibbling over small differences. What exactly is the problem you are attempting to solve? It seems that this is becoming an academic exercise rather than one to solve a real-world problem.
That said, look at the 'df' and 'bdf' manpages. From 'df(1M)', "The df command displays the number of free 512-byte blocks and free inodes available for file systems by examining the counts kept in the superblock or superblocks." In contrast, from 'bdf(1M)', "Non-HFS file systems may have other items not accounted for by this command."

thank you
i have a large fs and "df" reports 100 % usage , "bdf" 99 % usage :
sorry, maybe i am quibbling over small differences.
i was looking about a command to save easy in a shell variable the value of the block device size .
i thought , this would be a short task , i know "bdf" and "df" and i hope that a perl function will exist ...
perl module exists, but not in a core module , so i read "bdf" and "df" man pages and then i detected those
difference above :-( i asked also my colleagues , they had also no explanation.
From 'df(1M)' : there are a lot of options, which i didn't know it before and i read it exactly and only "df -g"
shows exact the same value (without multiply , divide ..) like "bdf"
you explain the difference very good , so i understand it know.
finaly , i also don't like to write a degree dissertation about those commands !
so i will stop it now and thanks to your great response

Re: how can i get size of block device (perl, shell script)
Hello,
Why reinvent the wheel when you can use simle tools native to HP-UX:
# /opt/ignite/bin/print_manifest
...
File System layout
LVM Device file mount point size fs type
/dev/vg00:
/dev/vg00/lvol1 /stand 1792 vxfs
/dev/vg00/lvol2 swap 4096
/dev/vg00/lvol3 / 95584 vxfs
/dev/vg00 unallocated 0
/dev/vg01:
/dev/vg01/lvol10 /guests1 149984vxfs
/dev/vg01 unallocated 3584
Or,

All these commands can pe parsed and proper information extracted easily.

Re: how can i get size of block device (perl, shell script)
I'm in the middle of a discussion with the author of the "Disk Info" utility di which is also available for HP-UX..
This utility works on HP-UX as well as on all other Unix-like OS's and gives the output the same on allOS's.
I've talked him into implementing a new -c option to generate the output as csv, so it is extremely easy to parse.
If you are interested, keep your eyes open on http://www.gentoo.com/di/

Re: how can i get size of block device (perl, shell script)
hello VK2COT,
@ Why reinvent the wheel when you can use simle tools native to HP-UX
@ All these commands can pe parsed and proper information extracted easily.
i have been working with HP-UX for many years and i have never heard about those commands !!!!
These are great commands and easy to parse !
Does a white paper exists about those commands ? I didn't find man pages !
i use for example :
/usr/sam/lbin/fslist -p /tmp
and i can interprete many columns , but when i have informations what column include what value it is easier !
regards

Re: how can i get size of block device (perl, shell script)
Hello,
It is my pleasure to share information.
Yes, I know that these commands are not known to majority of users :)
I am a Senior Instructor in HP Education and IT Architect in Australia/New Zealand
(teaching all sorts of HP-UX, Solaris, LInux (Red Hat, SUSE and Ubuntu), 3PAR,
ServiceGuard, Data Protector, EVA and Ibris X9000 NAS courses. I am also
a Wordwide Unix Ambassador and Unix Profession Leadership team at HP
so it is lot of fun for me to work on unsual things.
Unfortunately, there are no manuals on these rare commands that I listed yesterday..
Some of the commands in ./usr/sam/lbin and Shell scripts and the only way to
learn what they do is to look into them.
Let me show some other intresting commands in this directory:
# paginglist
/dev/vg00/lvol2|dev|4194304|4.0 GB|0|0.0 KB|4194304|4.0 GB|0%|0|-|1|no|now|
reserve|reserve|0|0.0 KB|3667436|3.5 GB|-3667436|-3667436`KB||0||0|no|now|
total|total|4194304|4.0 GB|3667436|3.5 GB|526868|514.5 MB|87%|0|0|0|no|now|
# importablevgs
1:/dev/disk/disk11_p2
And then new way to check ServiceGuard:
# /opt/OV/bin/ovclusterinfo -a
This command supports other types of clusters:
- Microsoft Clustering Services (Windows)
- MC/ServiceGuard (HP-UX)
- VERITAS Cluster Server (Solaris)
- Sun Cluster (Solaris)
- TRU64 Cluster (TCR)
- Red Hat Advanced Server (RHAS)
- HACMP (AIX)
- Unknown.
If you want to learn more of the "unusual" commands take a look at my
Operations Acceptance Testing Perl script for HP-UX:

Cheers,
VK2COT

Re: how can i get size of block device (perl, shell script)
After maybe 40 mails with the author of di, I am glad to say that the just release new version 4.29 works on all HP-UX that I could access, ranging from 10.20 +DAportable to 11.31 with gcc/64
I have uploaded the depots to my site which should be in sync within 20 hours, so feel free to grab your copy. Some examples:
$ di -l -c s,m,b,u,v,p,T /dev/vg00/root,/,"400.0M","333.2M","66.3M",83%,vxfs /dev/vg00/data,/data,"12.0G","11.3G","0.6G",95%,vxfs /dev/vg00/home,/home,"512.0M","265.1M","246.9M",52%,vxfs /dev/vg00/opt,/opt,"6.5G","6.1G","0.4G",95%,vxfs /dev/vg00/pro,/pro,"24.0G","22.2G","1.8G",93%,vxfs /dev/vg00/stand,/stand,"304.0M","183.2M","119.9M",61%,vxfs /dev/vg00/tmp,/tmp,"2.0G","0.8G","1.2G",40%,vxfs /dev/vg00/usr,/usr,"5.3G","2.2G","3.1G",42%,vxfs /dev/vg00/var,/var,"4.5G","1.8G","2.7G",41%,vxfs /dev/vg00/wrk,/wrk,"1.0G","0.3G","0.6G",37%,vxfs $ di -c >di.csv $ env DBI_DSN="dbi:CSV:f_ext=.csv/r" qs -L f di w p '>' 90 SCHEMA: merijn, TABLE: di [.] select s, m, b, u, v, p, t from di where p > '90' s |m |b |u |v |p |t /dev/vg00/data|/data |12.0G|11.3G|0.6G|95%|vxfs /dev/vg00/opt |/opt |6.5G |6.1G |0.4G|95%|vxfs /dev/vg00/pro |/pro |24.0G|22.2G|1.8G|93%|vxfs $
qs is a perl script that acts as a command-line SQL query interpreter (qs = quick select), and used here just to demonstrate how easy the output of the new -c option for di is parsable (as a database).
