df command

[kholikt]

Hi,

I am using df -k to show all the disk space and usage of the filesystem. Is there anyway that I can display the disk space in MB format rathan KB

This will do it.

modify this which parses bdf output.

#!/usr/bin/ksh

echo "Filesystem Mbytes used avail %used Mounted on"

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


#!/usr/bin/ksh

echo "Filesystem Mbytes used avail %used Mounted on"

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


You have to mess with it so that it gets the kb figure divided by 1024. It can be done.

actually i was confused. I was thinking about the du command.

I suppose with enough contortions my poorly explained post can be useful.

Hi,
what is the O.S.
In Hp try bdf or
in Linux try

df -H

I think you'll find bdf much more useful than df -k. And the attached script is called bdfmegs which will report everything in megs (try the -v option)

Hi,

Thanks for the reply I have notice your script is very useful but not easy to parse

echo "Filesystem Mbytes used avail %used Mounted on"

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

I need to convert the output to a CSV file but the output simply generate too much spaces in between the field.

Hi,

I get confuse when you say disk space because it is not equal to filesystem space.
Anyway bdf is the best command in order to see the filesystem space (total size, used and available space).
Anyway the best command in order to see the used space is 'du -sk'; option -k stands for Kbytes. It is more reliable about the used space of a filesystem than bdf.

HTH.

Best regards,

Hi,

If you want to see the file system size in MB, you can use lvdisplay. For finding out freespace, used space, available etc. bdf is best.
