I've recently found out about a somewhat unituitive behaviour in ls. Execute the following commands:
bash> LANG=en_US.utf-8 bash> touch vi-mode vima vimz bash> ls vi-mode vima vimz vima vi-mode vimz The strange sort order in the output of ls is there because ls uses strcoll to perform sorting, and strcoll seems to only sort on alphabetic characters and ignore e.g. '-', hence 'vim' and 'vi-m' are considered equvalent. I realise that collation is different in unicode than in plain C, and I can see why one would sort e.g. 'a' and 'A' together, but completely ignoring hyphens and other nonalphabetic characters seems to be a very unreasonable behaviour. Manual pages for strcoll do not explicitly state if non-alphabetic characters should be considered, only that the collation order specified by LC_COLLATE should be respected, so I'm not sure if this is a strcoll bug, a ls bug or simply dissonance between the two, but I think this behaviour is clearly suboptimal, so I thought I'd report it. -- Axel _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
