Git Restore Documentation Default Source Index Head Official
The git restore documentation default source index head official rule sets the source by target. Restoring the working tree pulls from the index, while restoring the index pulls from HEAD. Teams often run this command on shared servers or local setups to undo bad edits. When server roles are too broad, a user can wipe out live files by mistake. Knowing where the tool pulls data from stops data loss during quick fixes. How git restore documentation default source index head official rules work

How git restore documentation default source index head official rules work
Git splits your local files into three main areas during daily work. You have the working tree, the staging index, and the last commit known as HEAD. The restore tool moves file content from one area to another to undo changes. It picks a default source based on which area you ask it to fix.
When you restore a regular file, the tool targets your working tree by default. In this case, the tool reads the file version stored in the staging index. It copies that staged version over your current working file on the disk. Any local edits made since you last staged the file go away for good.
When you tell the tool to restore the staging index, the source changes. The tool now looks at HEAD, which is the tip of your current branch. It copies the committed version of the file back into your staging index. This action unstages your changes but leaves your working tree files untouched on disk. You can also tell the tool to update both places from HEAD at once.
Why source selection matters for team workflows
Mixing up the staging index and HEAD causes headaches for engineering teams. A user might think they are pulling a clean file from the last commit. Instead, they pull a broken edit that they staged ten minutes earlier. If they ask to restore both areas from HEAD, they wipe out staged work.
This confusion gets worse when engineers debug issues on shared cloud servers. Teams often log in to a host to check code or fix a script. If they run the wrong restore action, they can overwrite hotfixes on that machine. Standard system roles only check who can log in to the server. Those roles do not check which files a user resets once inside the shell.

What native source controls solve and what they leave open
Built-in version control rules give users fine control over local code states. The split between the index and HEAD lets you undo work in small steps. You can clear out bad experiments while keeping good staged work safe. Native repo permissions also decide who can push commits to shared branches.
Still, local git rules and host logins leave a big operational gap open. Host permissions only decide who can open a shell session on a server. They do not inspect or control individual commands run during that live session. If a user has write rights on a folder, they can overwrite any file. Native setups also do not log which commands a user ran on the host. When a file changes on a live server, teams cannot see who ran what.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
Where does git restore pull from when I only give a file name?
It pulls the file content from the staging index by default. It overwrites the file in your working tree with that staged version.
How does the default source change when I unstage a file?
When you target the staging index, the tool pulls from HEAD instead. This resets the staged file to match your last commit on that branch.
Does restoring from HEAD delete my local uncommitted work?
If you only target the staging index, your working tree files stay safe. If you target the working tree using HEAD as the source, local edits vanish.
