btrfs qgroup show -re

The result is for all subvolumes, then just find the subvolume you need.

Thanks,

I need to use the quota number in a script... is there a more specific
command, otherwise I need to get the groupID first and then to parse the
output...

Thank you!

IIRC "btrfs qgroup show -re <mnt>" is specific enough.

Just try it, and read btrfs-qgroup(8).

As long as you're using it in a script, the you will need subvolume id
anyway.

AFAIK you don't need subvolume id, `btrfs qgroup show -ref 
/path/to/subvolume` shows necessary qgroup for me. Separating value you 
need is more involved:

> btrfs qgroup show -ref --raw /path/to/subvolume | tail -n +3 | tr -s ' 
> ' | cut -d ' ' -f 4
Not sure how robust is this though.
