Hi!
How to get free space left on file system /var/opt/ignite/recovery/archives
from the following output?

Hi Igor,

You can try this,

# bdf /dev/vg01/ignite | awk '{a+=$4} END {printf "%d\n",a}'

Try following command :

bdf |grep -i /var/opt/ignite/recovery/archives |awk '{print $4}'

output will be in KB

hi igor,
this u can use and get the bdf result in mb.
============================================================
#!/usr/bin/ksh

echo "Filesystem Mbytes used avail %used Mounted on"

bdf | grep -v Filesystem | awk '{ printf("%s %10d %10d %10d %4s %s\n",$1,$2/1024,$3/1024,$4/1024,$5,$6)}'

Wow, I'm surprised that no one suggested the simplest method:

bdf /var/opt/ignite/recovery/archives

No grep, no awk, nothing but bdf. You could pipe the second line from bdf into read and extract just the free space:

bdf /var/opt/ignite/recovery/archives | while read HEADER REPLY
do
if [ "$HEADER" = "Filesystem" ]
then
read DEV CAP USED FREE PCT FS
MEGSFREE=$(echo $FREE | awk '{print int($1/1024+.5)}')
echo "$FS has $FREE Kbytes ($MEGSFREE megs) free space"
fi
done

The above shows both Kb and megs.

Hi,

I think Igors problem was the 2line-output of the bdf command for long device names; Bills response will handle that.

To get a bdf-like 1line-output for further processing in all cases, I suggest (untested):

bdf | awk 'NR>1 {if(ok) print line; ok=0;line=$0}
NF==1 {line=line" "$0;ok=1}
NF>5 {ok=1}
END {print line}'

Peter pointed out that I did not test for a long line in a bdf listing. There is an inserted test for a null size and a second read to get the second line. This is common a problem with NFS filesystems (long source names):

bdf /house | while read HEADER REPLY
do
if [ "$HEADER" = "Filesystem" ]
then
read DEV CAP USED FREE PCT FS
[[ "$CAP" = "" ]] && read CAP USED FREE PCT FS
MEGSFREE=$(echo $FREE | awk '{print int($1/1024+.5)}')
echo "$FS has $FREE Kbytes ($MEGSFREE megs) free space"
fi
done
