The fastest way to lose twenty minutes is
The fastest way to lose twenty minutes is typing git pull in the folder above your repo. Git answers fatal: not a git repository (or any of the parent directories): .git, and most answers online reply with git init — which is wrong for three of the four real causes.
--show-toplevel prints your repository root when one exists
--show-toplevel prints your repository root when one exists above you: wrong directory, case closed, cd there. When it fails too, the same line lists the folder's contents: no .git in that list means there was never a repo here to find. That single command separates the two causes behind most occurrences. The rest of this post is the smaller cases. Why does Git say "fatal: not a git repository"?
Git finds a repository by walking up from
Git finds a repository by walking up from the current directory, hunting for a .git entry, and stops at the first one. That walk breaks in exactly four ways: you stand outside the tree, the .git folder is gone, an environment variable redirects the search, or .git exists but points at nothing. Stack Overflow's 2022 Developer Survey put Git on roughly 94% of developer machines, so the error is a shared rite of passage. Learn the four cases once and they stop costing time.
(If your repo is fine and you actually
(If your repo is fine and you actually came here to undo a commit, Undo Anything in Git collects every repair path on this site in one place.) Case 1: you are in the wrong directory The common one. Two shapes:
You cd'd into a subfolder (docs/, src/api/) and
You cd'd into a subfolder (docs/, src/api/) and the shell habit from another project says the repo root is here. Git walks up, finds nothing, quits.
You cloned a repo and expected the files
You cloned a repo and expected the files here, but git clone always creates a subdirectory named after the repo. The checkout sits one level below where you're standing. The second command is the permanent fix for the muscle-memory problem: it works from any depth inside the repo. Case 2: there is no .git — the folder never was a repo ls -a shows no .git. Usually one of:
A GitHub ZIP download. Code → Download ZIP
A GitHub ZIP download. Code → Download ZIP ships the files only: no .git, no history, no remote. GitHub's own docs confirm the ZIP archive contains the source snapshot alone. Files copied in from a machine or another project, without the hidden folder. A cleanup tool deleted .git as "hidden junk". Fix: re-clone to recover the history.
git init here starts a fresh repository; nothing
git init here starts a fresh repository; nothing is recovered. And the copied-files mess usually drags untracked strays with it; git remove untracked files covers the cleanup once the clone is in place. git init doesn't repair a repo — it creates an empty one where you stand. git init doesn't repair a repo — it creates an empty one where you stand. Case 3: GIT_DIR is set, and breaks every repo
The tell: the error follows you into directories
The tell: the error follows you into directories where Git worked an hour ago. An exported GIT_DIR tells Git to look at one fixed path instead of discovering the repo, so every "ordinary" directory becomes "not a repository".
