This isn't really a satisfactory rationale IMNSHO, and the chain of
links you just sent me down is basically a bunch of echoing the same
incredibly weak rationale.
I recently tripped over this when just wanting to watch a directory of
video files in ascending file size order. A simple `ls -Sr | xargs
mpv` would do the trick, but the filenames turned out to be a real
mess warranting -0. Trivial to add -0 to the xargs, but not so for
the ls command, wasting significant time digging through its man page.
Are we really expecting a user in this situation to then go read the
find(1) man page and figure out how to prevent it from recursive
operation, produce null termination, *and* sort the results by file
size in ascending order?
When they already have the exact `ls -Sr` invocation in hand?
This seems asinine to me, the entire unix philosophy is composable
utilities and ad-hoc pipelines. `ls` is arguably the most familiar
and reflxively used of those utilities. I see no reason to prevent
the user from making its output robust against newlines in pipeline
scenarios like the one described above. Especially considering a
patch has already been submitted to add it...
Thanks,
