With the concerns about your bash prompt registered... btrfs filesystem show ... is a good choice. If you have multiple filesystems you can point show at a device/ mountpoint/label/UUID to get the output for just the one. You'll want to pay particular attention to the individual device lines. Of course you can grep/sed/otherwise-process that down to a single line if desired. If btrfs filesystem show says it's close to out of room, run btrfs filesystem df for more info. There's lots of information on the wiki and in various threads here about interpreting the information these commands output (it takes both commands to get a good picture, but show is good for brief summary, provided you know to look at the device lines not the overall total line), and what to do when necessary to return some balance to the situation. -- Duncan - List replies preferred.
