bdfmegs ver 5.3

[Bill Hassell]

Hi all. The latest bdfmegs is now available (attached) and has a much needed option to change the divisor between 1024 and 1000. The default is now 1000 (was 1024) but a one line change can be used to change the behavior back to 1024. Additionally, the -d option will toggle the default divisor to the opposite value.

Here's the -h (help) option:

Usage: bdfmegs [ -cdghlNPpqstuVv ] [ ]
where:
-c # = Sort on column #
-d = Toggle divisor (1000 or 1024, current=1000)
-g = show gigabytes, otherwise megabytes
-h = Usage (return code=0, Usage to stdout)
-l = local (no NFS)
-N = skip one or more volume groups
Repeat -N or use commas: -N vg10,vg24
-p ## = highlight % -ge ##
-P ## = show only % -ge ##
-q = suppress header line and no char enhancements
-s = summarize total, used and available
-t = specifc filesystem: (hfs vxfs nfs cdfs cifs autofs DevFS)
-u = usage (return code=0, Usage to stdout)
-v = verbose (type, version, largefiles)
(version info read permission for mountpoint)
-V = select one or more volume groups
Repeat -V or use commas: -V vg00,vg01

File(s) or dirpath(s) may be specified to reduce the output of bdfmegs:

bdfmegs -vg /usr/contrib/bin /var/tmp

If bdfmegs is run as bdfgigs (ie, a link), then -g is default.

thanks Bill,
i had downloaded it and will try with one of my test unix system.

i think in this update -V option is very usefull,

thanks again.. :)

Thanks Bill.
This is not only a good tool, but a good example of shell programming as well.
Rgds,

Thank you Bill, I tried previous version and it was good. Now I will try this.

Hi,

I tried -d switch, could you please look at the output in my 11i v1 HP-UX server:

# ./bdfmegs -vd /usr/contrib/bin /var/tmp
File-System Mbytes Used Avail %Used Type Vr Lrg Mounted on
/dev/vg00/lvol8 2048 1414 628 69% vxfs 4 yes /usr
/dev/vg00/lvol9 2048 833 1205 41% vxfs 4 yes /var

# ./bdfmegs -v /usr/contrib/bin /var/tmp
File-System Mbytes Used Avail %Used Type Vr Lrg Mounted on
/dev/vg00/lvol8 2097 1448 643 69% vxfs 4 yes /usr
/dev/vg00/lvol9 2097 853 1234 41% vxfs 4 yes /var

-different MB(s) ,so I admit that I could not quite catch the reason for this, can you explain why added this workaround ?

In the first output, using the '-d' switch, it is forcing the use of 1024 as the divisor for figuring MB and GB. Your output shows the the LVOLs are '2048 MB' (2 GB) which is 2,097,152 KB / 1024.

The 2nd output is using 1000 as the divisor. Thus it is showing 2,097,152 / 1000 = 2,097 MB for your LVOLs.

Sorry Hakki, I messed up your points - you deserve 8 for asking a common question. Patrick beat me to the answer. If you compare bdf to bdfmegs (ver 5.3), the numbers will match. The 1024 option is not that useful

[Hakki Aydin Ucar]

I got the answer. it is a matter of resolution for me. Thanks for the replies.

No matter point I received.

Regards.

Bill, I have been using bdfmegs for some time now, and find it extremely useful. At times I have multiple snapshot filesystems mounted, which truly are only built at 10% of the actualy filesystem. However, in bdfmegs they appear as the identical size of the original (rather than the 10%). All of my snap lv's are names as such (/dev/vgtrn/lvtprepip_snap) always mounted to a /backups mountpoint. Is there any way that these could be excluded from the TOTALS calculation that bdfmegs does so well? Thanks in advance!
