+#Clone a specific branch
+
+There are many cases where we want to clone a particular branch. For those, we need to run the following command:
+
+````
+// E.g. git clone -b <branch_name> <remote_repo>
+git clone -b wiki bugfixing
+````
+
+
+In the following, please note how a public key setup is required. If you don't have a public key already set, you can also clone by using this: 
+
+```
+// Example, with OpenCV 2.4 branch:
+git clone -b 2.4 --single-branch https://github.com/Itseez/opencv.git opencv-2.4
+```

+#Git Pull vs Git Fetch:
+
+These two commands are regularly used by git users. Let's see the difference between both commands.
+
+
+For the sake of context, it's worth remembering we're probably working in a clone repo. What's a clone? simply a duplicate of another repository. 
+It is basically getting your own copy of someone else's source code.
+
+That said, to keep your clone updated with whatever changes may have been applied to the original, you'll need to bring those to your clone. That's where `fetch` and `pull` come in. `git fetch` is the command that tells your local git to retrieve the latest meta-data info from the original (yet doesn't do any file transfering. It's more like just checking to see if there are any changes available). `git pull` on the other hand does that AND brings (copy) those changes from the remote repository.
+
+E.g.
+```
+git pull origin ankur bugfix         
+```
+
+The take away is to keep in mind that there generally are at least three copies of a project on your workstation. One copy is your own repository with your own commit history (the already saved one, so to say). The second copy is your working copy where you are editing and building (not committed yet to your repo). The third copy is your local "cached" copy of a remote repository (probably the original from where you cloned yours).
+You can use `git fetch` to know the changes done in the remote repo/branch since your last pull. This is useful to allow for checking before doing an actual pull, which could change files in your current branch and working copy (and potentially losing your changes, etc).
+
+```
+git fetch    
+git diff ...origin
+```

-A clone is simply a copy of a repository. It is something like where you can download source code from some other repository.
-<b>git fetch</b> is the command that says "bring my local copy of the remote repository up to date."

-Normally when use <b>git pull</b> , it does the same thing done by <b>git fetch</b> to bring the local copy of the remote repository(up-to-date), and then merging the changes into own code repo.Example

-Git allows you to set aliases but they’re limited and only save you a few keystrokes (i.e. instead of git checkout you can type git co, but you still have to type git). Since Bash is Terminal’s default command-line interpreter, you can also set Bash aliases to reduce your keystrokes even further.

 When copy & pasting, it’s important to keep the spacing. (i.e. for aliases, there must be no spaces before and after the equal signs, and for functions, there must be a space after the opening curly bracket of the declaration and a semicolon after the command. Don’t forget to reload your file (source ~/.bash_profile) or restart Terminal after making changes.
