bdf one line output

[Vishu]

Hi Guys,

I have HP-UX 11.00 server. Below is the bdf output of it.

$ bdf

As you can see above, the last two FS of bdf comes in separate lines, but we run one script that need to have the one line output for every FS, and all fields of bdf are mandatory. That script is scheduled and run on many other servers also. I tried df -kp, but no use.

Is there anyway that we can get the one line output of every FS in bdf or any other command.

Thanks

Hi:

This question arises frequently.

You could use:

# bdf | awk '{if (NF==1) {line=$0;getline;sub(" *"," ");print line$0} else {print}}'

OR:

You could avail yourself of a richly functional script by Bill Hassell which accomodates your requirement and much, much more. Bill's most recent version (5.2) is attached at the end of this thread:

Hi,
The best utility is bdfmesg created by Greate Bill H.
I am attaching the script download and enjoy..and thanks to Bill.

Split lines from bdf are always a problem, but there is an easy scripting method to handle it. Basically, you read the first line then check the 2nd variable (lvol size). If it doesn't have a value, read the rest of the values, like this:

bdf | while read FS TOT USED AVAIL PERCENT MNT
do
if [ $FS != "Filesystem" ] # skip the header
then
if [ "$TOT" = "" ] # must be a split line
then
read TOT USED AVAIL PERCENT MNT
fi
# here's the output
echo $FS $TOT $USED $AVAIL $PERCENT $MNT
fi
done

Attached is the latest version of bdfmegs. I made a change to the divisor from 1024 down to 1000. This makes the output match bdf. For your script to monitor space, you may find options -qP90 vey useful to provide a list of filesystems greater than 90% full and without any header:

bdfmegs -qP90

bdfmegs can also look at specific volume groups (-V option) or ignore specific volume groups (-N option).
