Commands For NewGits

Here are a number of the essential command line git commands that can be used for working on shared repos in corporate environments. I use a combination of commandline and visual tools to manage my git repos and source code, and find it the perfect combination of power, speed and capability.

In a bind (or on a remote server via ssh) you can easily get by with just the commandline.

Assumptions and Prerequisites

  • You have a local repo or a central bare repo and a number of developers pulling and pushing to the central repo.
  • You have the commandline version of git installed on your corporate windows laptop/desktop. Don't worry if you are languishing on XP on a large corporate or government client network, git will work there very nicely indeed.
    • If you are on linux use your package manager to pull down the latest version of git (e.g. on Ubuntu use sudo apt-get install git-core)
