With stat 8.13 on a Debian based Linux - among many others - the following FORMAT directives (--format=) are offered:
In combination with --file-sytemsystem (-f):
%sBlock size (for faster transfers)%SFundamental block size (for block counts)
Question(s): What exactly is meant?
My best guess is that %s, %S equals %b (dispalydisplay in Blocks) and %B (display block's size), where the latter are for files and the first two are for file systems. Is that correct?
