Hi, I believe there is a bug in git status that happens when a file changes but the filtered version of the file does not. Correctly, git diff does not show anything as different and git commit believes there is nothing to commit. Reproducer: $ git init $ touch bar $ git add bar $ git commit -am 'Bar' [main (root-commit) dd12b3e] Bar 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 bar $ echo -en '\n[filter "noat"]\n clean = grep -v "@"\n' >> .git/config $ cat .git/config [core] repositoryformatversion = 0 filemode = true bare = false logallrefupdates = true [filter "noat"] clean = grep -v "@" $ echo -en 'abc\n@def\nghi\n' > bar $ cat bar abc @def ghi $ echo "* filter=noat" > .gitattributes $ git commit -am 'No at bar' [main e81ee3b] No at bar 2 files changed, 3 insertions(+) create mode 100644 .gitattributes $ git show HEAD:bar abc ghi $ echo "@another line" >> bar # Add another @ which will be filtered. touch doesn't cause this bug $ git status --porcelain M bar $ git diff # no output as there is no diff $ git commit -am "I did not update" On branch main nothing to commit, working tree clean While this reproducer is a bit contrived, the real world examples are with Jupyter notebooks filtering output, so I expect this is a somewhat common occurrence. I think it also may be the same as https://stackoverflow.com/questions/62641222/how-to-make-git-status-consider-the-clean-filter. Git version: 2.35.1 OS: Linux Note: I also logged this here, but I believe this mailing list is the correct place to raise the issue: https://github.com/gitgitgadget/git/issues/1256 Thanks, Marc
