Get remaining disk space from df's output

I would like to get the remaining disk space in my home directory:

df -h
Filesystem      Size  Used Avail Use% Mounted on
rootfs           20G   15G  3.5G  81% /
/dev/root        20G   15G  3.5G  81% /
devtmpfs        990M  4.0K  990M   1% /dev
none            199M  2.7M  196M   2% /run
none            5.0M     0  5.0M   0% /run/lock
none            991M   12K  991M   1% /run/shm
/dev/sda2       894G  847G  1.9G 100% /home

Note: All I need from the output above is 1.9G

Solution

  • use grep to take only the /home line, and awk to get only the field you want:

    df -h | grep -w /home | awk '{print $4}'
