From 0fc8e78088216c76c262b1ea723d7136ec191869 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Holger=20Hoffst=C3=A4tte?= Date: Sat, 30 Sep 2017 17:54:27 +0200 Subject: btrfs-progs: right-align number columns in btrfs-debugfs output MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The values for block group offset, length etc. in btrfs-debugfs' output are left-aligned, which creates unaligned output and makes the usage percentage hard to read/process further. This patch adds right-aligning format specifiers for the number values. Ideally the format values wouldn't be hardcoded but instead derived from the filesystem size, but this seems to work for now.
