Thanks for the report.

od -cx is not always the best choice in formatting - it depends on the
endianness of your machine since it groups two bytes at a time. I
personally like 'od -c -tx1z' better for the type of output you are wanting.

What trailing space? Your output ended in space, slash, dot, newline,
with no trailing 0x20. The half-word 2f20 in od -x output means that
space (20) comes _before_ slash (2f) on your little-endian machine, not
If you actually have a case where ls results in trailing space, then
yes, that's a bug we'd like to fix, but you haven't demonstrated that.
But you are right that POSIX does not permit a trailing space after the
file name in -l output.

I'm afraid you're chasing after a wild goose. ls isn't outputting a
trailing space in the first place, so this can't be the cause of your
I'm marking this bug closed for now; you can reopen it if you can
demonstrate an actual bug with trailing space.
