In the manual for Gnu "ls," I see this:
--author
with -l, print the author of each file
Does anybody know what the “author” of a file means in this context?
This is (maybe?) not the file's owner, which is listed already with -l … or is it? Perhaps this refers to a different type of filesystem than mine (ext4), that has a distinction between "author" and "owner?"
On my machine, it seems to uniformly duplicate the "owner" column, but I'm definitely curious about this one.
Perhaps this is just the worst combination of "noise" keywords ever, but I can't find anything relevant online (neither /usr/share/{man,info} nor StackExchange nor Google), but “author” is practically a noiseword :-(
I suppose, if all else fails, I can dig through the coreutils sources…
