Btrfs-progs: enhance btrfs qgroup show to sort qgroups
You might want to list qgroups in order of some items, such as 'qgroupid', 'rfer'
and so on, you can use '--sort'. Now you can sort the qgroups by 'qgroupid',
'rfer','excl','max_rfer' and 'max_excl'.
For example:
If you want to list qgroups in order of 'qgroupid'.
You can use the option like that:
btrfs qgroup show --sort=+/-qgroupid <path>
Here, '+' means the result is sorted by ascending order. '-' is by descending
order. If you don't specify either '+' nor '-', the result is sorted by
default - ascending order.
If you want to combine sort items, you do it like that:
btrfs qgroup show --sort=-qgroupid,+rfer,max_rfer,excl <path>

Btrfs-progs: enhance btrfs qgroup show to sort qgroups
You might want to list qgroups in order of some items, such as 'qgroupid', 'rfer'
and so on, you can use '--sort'. Now you can sort the qgroups by 'qgroupid',
'rfer','excl','max_rfer' and 'max_excl'.
For example:
If you want to list qgroups in order of 'qgroupid'.
You can use the option like that:
btrfs qgroup show --sort=+/-qgroupid <path>
Here, '+' means the result is sorted by ascending order. '-' is by descending
order. If you don't specify either '+' nor '-', the result is sorted by
default - ascending order.
If you want to combine sort items, you do it like that:
btrfs qgroup show --sort=-qgroupid,+rfer,max_rfer,excl <path>
