以下是一些好用的 Btrfs 相关的程序。
=== [https://github.com/kilobyte/compsize compsize] ===
查看 <code>/</code> 的压缩类型和压缩前后的大小
sudo compsize /
=== [https://github.com/knorrie/btrfs-heatmap btrfs-heatmap] ===
查看 <code>/mountpoint</code> 的 heatmap
sudo btrfs-heatmap /mountpoint
=== [https://github.com/speed47/btrfs-list btrfs-list] ===
查看树形的 snapshot 列表
<syntaxhighlight lang=bash>
sudo btrfs quota enable /
# 等待 quota rescan
sudo btrfs-list
sudo btrfs quota disable /
</syntaxhighlight>
=== btrfs-diff ===
查看第二个 subvolume 相对于第一个改变的文件
sudo btrfs-diff /mnt/_snapshots/%home/snap /mnt/@home
脚本如下（拷贝自 https://serverfault.com/a/580264<nowiki/>）
<syntaxhighlight lang=bash>
set -eu
usage() {
echo "Usage: $0 <older-snapshot> <newer-snapshot>" >&2
exit 1
}
[ $# -eq 2 ] || usage "Incorrect invocation"
snapshot_old=$1
snapshot_new=$2
[ -d "$snapshot_old" ] || usage "$snapshot_old does not exist"
[ -d "$snapshot_new" ] || usage "$snapshot_new does not exist"
old_transid=$(btrfs subvolume find-new "$snapshot_old" 9999999)
old_transid=${old_transid#transid marker was }
[ "$old_transid" -gt 0 ] || usage "Failed to find generation for $snapshot_new"
btrfs subvolume find-new "$snapshot_new" "$old_transid" | sed '$d' | cut -f17- -d' ' | sort | uniq
