git add -u

Configuring Git (Local Machine)

User Level Configuration

git config --global

git config

Stored in .git/config in each repo.

History of Version Control Systems

Single File Systems 

Users could make their own revisions of a document, commit changes, and merge them together. However, these systems (e.g. TCS) operates only on single files. It has no way of working with an entire project, so it does not support atomic commits affecting multiple files. 

Examples include SCCS, RCS etc.
