My immediate thought was "that is simply a bug, no?" :-D I haven't used 'git ls-files' that much, so it's no great surprise that I had not noticed it odd behaviour! So, this evening, I decided to have a little play: $ git status On branch master You have unmerged paths. (fix conflicts and run "git commit") (use "git merge --abort" to abort the merge) Changes to be committed: new file: d Unmerged paths: (use "git add <file>..." to mark resolution) both modified: a Changes not staged for commit: (use "git add/rm <file>..." to update what will be committed) (use "git checkout -- <file>..." to discard changes in working directory) modified: b deleted: c Untracked files: (use "git add <file>..." to include in what will be committed) e $ git ls-files a a a b c d $ git ls-files -c a a a b c d $ git ls-files -m a a a b c $ git ls-files -d c $ git ls-files -u 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a $ git ls-files -s 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a 100644 4f2e6529203aa6d44b5af6e3292c837ceda003f9 0 b 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c 100644 72ad562535b8551cdd6659e8fb6c7cf6830e6a07 0 d $ git ls-files -sd 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a 100644 4f2e6529203aa6d44b5af6e3292c837ceda003f9 0 b 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c 100644 72ad562535b8551cdd6659e8fb6c7cf6830e6a07 0 d 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c $ git ls-files -su 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a $ git ls-files -sm 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a 100644 4f2e6529203aa6d44b5af6e3292c837ceda003f9 0 b 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c 100644 72ad562535b8551cdd6659e8fb6c7cf6830e6a07 0 d 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a 100644 4f2e6529203aa6d44b5af6e3292c837ceda003f9 0 b 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c $ git ls-files -sdu 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c $ git ls-files -sdum 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a 100644 4f2e6529203aa6d44b5af6e3292c837ceda003f9 0 b 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c $ git ls-files -sdumo e 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a 100644 4ef30bbfe26431a69c3820d3a683df54d688f2ec 1 a 100644 af72a79d2a6bd4b252b0aca22dba9946f7eedf86 2 a 100644 f8829dfb9bf82721903d239ef069fb5de395f3e7 3 a 100644 4f2e6529203aa6d44b5af6e3292c837ceda003f9 0 b 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c 100644 a296d0bb611188cabb256919f36bc30117cca005 0 c $ Er, ... well, I obviously don't have a clue how it is supposed to work.
