Please, not this way.
Hi Hugo,
Just wanted to check which approach you'd prefer to see me adopt:
1. Providing an option which is handled near the entry point (prior
going to commands), which would toggle a global flag to indicate the
format.
2. An option in every function which uses pretty sizes. (Though -B seems
to be used by scrub, -b is used by calc-size and mkfs utils, -u is used
by subvolume list and so on, meaning the option might have to be
different for different commands)
3. An environment variable BTRFS_UNITS, which when set to b[ytes],
changes the behaviour of pretty printing. Avoids having to touch the
multiple sets of ad-hoc option parsing code, but is perhaps a slightly
non-standard interface.
Thanks,
Audrius.
