ls: Tab produces `\t` instead of `TAB` and the output is not sorted correctly. #5490

Closed allaboutevemirolive closed 11 months ago

Steps to reproduce:

touch "a........a"
touch "a....    a"
touch "a        .....a"
touch "aaaaaaaaaaa"
touch "aaaaaaaaaaaa a"
touch "aaaaaaaaaaaaaaaaa"
touch "a    ·····b"
touch "a├─┤·····b"
touch "test....test"
touch "test         test"

ls -Cw18 | batcat -A

./coreutils ls -Cw18 | batcat -A

Sample output:

$ ls -Cw18 | batcat -A

The issue with sorting is that uutils doesn't yet support localization and uses the C locale (see https://github.com/uutils/coreutils/issues/3997). And so the sorting results are usually different, unless you specify LC_COLLATE=C when calling GNU ls.

On my side, the issue is the same without the -Cw18 flags, which makes a smaller reproducible example. Most probably, this has to do with ls checking if stdout is a tty
