Technical notes

The contents of files are not actually stored in the index (.git/index) or in commit objects. Rather, each file is stored in the object database (.git/objects) as a blob, identified by its SHA-1 hash. The index file lists the filenames along with the identifier of the associated blob, as well as some other data. For commits, there is an additional data type, a tree, also identified by its hash. Trees correspond to directories in the working directory, and contain a list of trees and blobs corresponding to each filename within that directory. Each commit stores the identifier of its top-level tree, which in turn contains all of the blobs and other trees associated with that commit.

Reset command

The reset command moves the current branch to another position, and optionally updates the stage and the working directory. It also is used to copy files from the history to the stage without touching the working directory.

If a commit is given with no filenames, the current branch is moved to that commit, and then the stage is updated to match this commit. If –hard is given, the working directory is also updated. If –soft is given, neither is updated.
