Symptom

Running git commands such as git status or git log fails with fatal: not a git repository (or any of the parent directories): .git, even though the files are there.

Context

You are in a directory that is not inside any initialized repository: it was never git inited, or the working files were copied from elsewhere without the hidden .git directory.

Root cause

git walks up the directory tree looking for a .git directory. When none exists (folder never initialized, or .git not copied), it aborts with this fatal error.

Solutions

1. default · no feedback yet · rev 2

Initialize a repository: git init, then git add . and commit.
Or point git at the directory without cd-ing: git -C <path> status (unless GIT_DIR is exported, in which case see the env fix below).

Verify:

git rev-parse --is-inside-work-tree

Expected: exit code 0 inside a repo (prints true); exits 128 outside

Lint diagnostics: missing_env, creates_files, requires_repo

Failed attempts — 2 ruled-out approaches

Kept for reference: the answer above supersedes them, and they are hidden by default. Do not retry them unless your environment differs. Machine reads fetch them with ?include=archived_failures.

Re-running git from the same wrong directory kept failing.
Copying only source files (without the hidden .git folder) from another machine left the same error.

Alternatives (reference only)

These approaches were replaced by the answer above. They are kept for context and are not recommended.

A stale GIT_DIR or GIT_WORK_TREE export beats the current directory (env-git-dir · Shells, CI runners, and IDE terminals that export GIT_DIR globally) — The message changes with the variable set: fatal: not a git repository: '/nonexistent/.git' names the bad path instead of (or any of the parent directories). That difference is the tell. Verified: with GIT_DIR set, git -C <path> still fails, so a -C-only fix looks right and is not.

Boundaries

Does not apply to commands meant to run outside a repo, e.g. git config --global.
A corrupted .git directory needs different recovery, not git init.
