With LVM and uuid devices, using df can be a pain:

    $ df
    Filesystem                                             1K-blocks     Used 
        Available Use% Mounted on
    rootfs                                                   3842376  1493404
        2153784  41% /
    udev                                                       10240        0
        10240   0% /dev
    tmpfs                                                     103384      204
        103180   1% /run
    /dev/disk/by-uuid/6832e4f5-a260-4f25-b376-7d7175bce2a9   3842376  1493404
        2153784  41% /

dff just calls df and trims the device part to make the output 
human readable again.

    $ dff.pl
    Filesystem    1K-blocks      Used  Available  Use% Mounted on
    rootfs          3842376   1493404    2153784   41% /
    udev              10240         0      10240    0% /dev
    tmpfs            103384       204     103180    1% /run
    uuid/6832e4f    3842376   1493404    2153784   41% /

IPC::Run Perl Module.

Debians: 

$ sudo apt-get install libipc-run-perl

RPMs:

#yum install perl-IPC-Run.noarch

Copy the file dff.pl to some directory in your path:

$ sudo cp dff.pl /usr/local/bin

Use it the same way you used df. It actually calls df, then it trims
the device part:

    $ dff.pl [ARGS]

If it runs well for you, use it from an alias, ie: .bashrc

    alias df=dff.pl

Even cleaner output:

    alias df=dff.pl -hP

dff own arguments

    If you use it as an alias, maybe one day you will need the real thing:
    
    $ dff.pl --real
    $ df --real # if you aliased df

    You can also change the length of the device part:

    alias df=dff.pl --length=19
