Help to Find out Available disk space
I need to find available disk space for /home.
Code:
$ df /home 
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mahhh/VolGroup11-LogVol00
                            32281452   45028  26034172  15% /

$df  /home  |tail -1| awk '{print $4}'
15%

The above result shows the Use% instead of Available as the df command output expands in 2 lines due to the Filesystem name

For single line output the results are fine... Any ideas how to get the available space in such cases ...

Thanks a lot for help

I'm pretty sure that the line doesn't get broken when piped.

The percentage displayed is the used percentage, not the Available percentage, perhaps you could subtract used from 100?

Force df to use POSIX mode, which is single-lined:
Code:
$ df /
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/system-root
                       2064208    490604   1468748  26% /
$ df -P /
Filesystem         1024-blocks      Used Available Capacity Mounted on
/dev/mapper/system-root   2064208    490604   1468748      26% /

You can aslo ust -hT option. It will show in human readable format and the fs type too.

Code:
root@cpaneltest [~]# df -hT
Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
              ext3    7.7G  6.4G 1011M  87% /
/dev/sda1     ext3     99M   25M   70M  26% /boot
/usr/tmpDSK   ext3    485M   14M  447M   3% /tmp
root@cpaneltest [~]#

Hi ,

The above command is very helpful
In linux we use : df -P
Similarly for HP-UX using bdf ,how do we get in to POSIX mode.

Thanks in advance
