Question

How can extract only “name” and “available space” from df linux command.

Answer 1

You can use…

df | tail -n +2 |  awk '{ print $1, $4 }' 

…assuming you don’t want the headers too. If you do, remove the tail.

We are piping df‘s output into tail, where we cut the first line off (the headers), and then pipe that into awk, using it to print the first and fourth columns.
