Basic Git Usage

@@ +1 @@
+This page contains a basic tutorial for working with git. There aren't any advanced concepts here, just the basics. In this tutorial we'll be working with a testing git repo and fake files.
+
+Its always a good thing to remember that while working with Git is a decentralized VCS, even though you may choose to push changes all to one server, you don't have to. Each repo contains a full history and set of objects in the .git directory.
+
+You will also only see a .git directory in the top level unlike svn where you have .svn in each sub directory as well as the top level.
+
+Unlike svn, git uses hashes to identify commits instead of revision numbers.
+
+These are just some basic tasks, the man pages can go into a lot more detail.
+
+=== Initializing a Git Repo ===
+
+Create a empty working directory:
+
+{{{
+mkdir git-tutorial
+cd git-tutorial
+}}}
+
+Initialize the local Git Repo:
+
+{{{
+git init
+}}}
+
+=== Committing files to the Repo ===
+
+Lets create a test file:
+
+{{{
+echo "Test Data" > testfile
+}}}
+
+Stage the file to be included into the next commit:
+
+{{{
+git add testfile
+}}}
+
+Finally commit the file to the repo:
+
+{{{
+git commit -m "Add a test file"
+}}}
+
+=== Viewing changes to files before committing them ===
+
+First lets make a change to our test file:
+
+{{{
+echo "Different Test Data" > testfile
+}}}
+
+View the changes:
+
+{{{
+git diff
+}}}
+
+You could also execute the following or something similar:
+
+{{{
+git diff testfile
+}}}
+
+=== Listing files with changes ===
+
+You can use the following command to list the status of all files not ignored by Git:
+
+{{{
+git status
+}}}
+
+You can also use the command on a path, the same as git diff.
+
+=== Revert a file back to a specified commit ===
+
+In this case we want to revert to the current working ref, so we wont specify one:
+
+{{{
+git checkout testfile
+}}}
+
+=== Reverting the entire working tree ===
+
+You can use the following command to revert the entire working tree to the last commit in the branch you're working with:
+
+{{{
+git reset --hard
+}}}
