Sort disk usage using df command

df-sort.sh

From: https://lists.gnu.org/archive/html/bug-coreutils/2007-01/msg00131.html


```
        df -Pk | tail -n +2 | sort -k3,3n
        
```

Or if you want to preserve the header, use a script like this:

        #!/bin/sh
        df -Pk > /tmp/df.$$
        (head -1; sort -k3,3n) < /tmp/df.$$
        rm -f /tmp/df.$$

another way to sort

df -B M | sort -k4 -g # sort by 4th field (Available) numerically
df -B M | sort -k5 -g # sort by 5th field (Use%) numerically

thanks for that, and a little improvement, make it human readable:

df -h | sort -k4 -h # sort by 4th field (Available) human-numeric-sort
df -h | sort -k5 -g # sort by 5th field (Use%) numerically
