Git basic commands why it's useless to use git to explain too much, if you really love programming, just follow the trend.

• A simple tutorial
• A slightly more detailed tutorial
• git authoritative guide
• Msys, Mgwin
• Gitolite is used for GIT server rights Management, which is based on SSH
• GitHub a public Git code management site, open source code of concentration camp

• Some of the most common git commands

  statusView the status of the current workspace
  logView historical records
  addadd files, commit all changes in the current directory git Add. –all (–all will also submit the deleted action)
  commitsubmit to local, general usage git commit-m "description of this submission"

• Tips for using

  The warehouse has Mater and Dev branches, the Mater branch is used to record the release record of the product version, each release of a version of a Tag,dev branch for the daily development of the submission code
  It is recommended that you set up your own temporary branch locally, each time you merge to Dev, so that even if you do something wrong, delete the temporary branch, it will not affect the code of others
  When preparing the push code, stash the GIT pull to update the remote code, then git stash pop, merge the conflicting files, add, Commit, push
  Develop a good habit of submitting a feature every time you complete a function to avoid accumulating too many files and conflict with others ' code.
