  7. About
  8. Who Created Git ? Git was initially designed and developed by Linus Torvalds for Linux kernel development in 2005 Git development began in April 2005 after many developers of the Linux kernel gave up access to BitKeeper Git meaning "unpleasant person" The man paqe describes Git as "the stupid content tracker"
  9. History e lifetime of the Linux kernel maintenance (1 991-2002) e In 2002, the Linux kernel project began using a proprietary DVCS called BitKeeper e In 2005, the relationship between the community that developed the Linux kernel and the commercial company that developed BitKeeper broke down
  10. Git Development Features Some of the goals of the new system were as follows: Speed Simple design Strong support for non-linear development (thousands of parallel branches) Fully distributed

  31. Git File Structure The SHA 6ff87c4664981 e4397625791 c8ea3bbb5f2279a3 The SHAI hash is a cryptographic hash function 40-character strings all over the place in Git
  32. Git File Structure Objects Git as a filesystem. It is content-addressable. Every object consists of three things - a type, a size and content Type of Objects BLOB Tree Object Commit Object Tag Object
  33. Git File Structure Objects A "blob" is used to store file data - it is generally a file. A "tree" is basically like a directory - it references a bunch of other trees and/or blobs (i.e. files and sub-directories) A "commit" points to a single tree, marking it as what the project looked like at a certain point in time. It contains meta-information about that point in time, such as a timestamp, the author of the changes since the last commit, a pointer to the previous commit(s), etc. A "tag" is a way to mark a specific commit as special in some way. It is normally used to tag certain commits as specific releases or something along those lines.
