Git processes the two pick commands (for pick 7b36971 and pick 6b2481b). When the editor is closed, the rebase continues: pick 1fc6c95 Patch A Otherwise, you have the option of changing the commit message by simply changing the text. If you're happy with these commit messages, you can save the file, and close the editor. This file is Git's way of saying, "Hey, here's what I'm about to do with this squash." It lists the first commit's message ( "Patch A"), and the second commit's message ( "something to add to patch A"). # with '#' will be ignored, and an empty message aborts the commit. # Please enter the commit message for your changes. The file it opens up looks something like this: # This is a combination of two commits. Since this operation requires your input, Git opens your text editor once again. It goes to the next command, squash fa39187. Git skips the first rebase command, pick 1fc6c95, since it doesn't need to do anything. Now, save and close the editor this will start the interactive rebase. We've changed each line's command from pick to the command we're interested in. Squash fa39187 something to add to patch A To start, we'll need to modify the commands in the file to look like this: pick 1fc6c95 Patch A Phew! This sounds like a lot of work, but by taking it one step at a time, we can easily make those changes. Fix the commit message of the misspelled commit ( 4ca2acc), using reword.Split the third commit ( dd1475d) into two smaller commits, using edit.Merge the "A fix for Patch B" commit ( c619268) into the "Patch B" commit ( 6b2481b), and disregard the commit message using fixup.Move the last commit ( 7b36971) up before the "Patch B" commit ( 6b2481b), and keep it as pick.Squash the fifth commit ( fa39187) into the "Patch A" commit ( 1fc6c95), using squash.Pick 7b36971 something to move before patch B Our favorite text editor will display the following lines: pick 1fc6c95 Patch A We'll start our rebase by entering git rebase -interactive HEAD~7 on the terminal. Modern hosted git solutions like Bitbucket support SSH key authentication.In this example, we will cover all of the git rebase commands available, except for exec. Git is capable of using SSH keys instead of traditional password authentication when pushing or pulling to remote repositories. Following this guide, you will be able to create and start using an SSH key. SSH keys are used to authenticate secure connections. If a linux subsystem is available the same steps previously discussed for Linux and Mac can be followed with in the windows linux subsystem. The windows linux subsystem offers a full linux shell within a traditional windows environment. Modern windows environments offer a windows linux subsystem. Once Git Bash is installed the same steps for Linux and Mac can be followed within the Git Bash shell. The most straight forward option is to utilize Git Bash. External shell programs will need to be installed for to have a complete keygen experience. Windows environments do not have a standard default unix shell. The new SSH key is now registered and ready to use! Generate an SSH Key on Windows execute the following to begin the key creation The process for creating an SSH key is the same between them.ġ. Generate an SSH Key on Mac and Linuxīoth OsX and Linux operating systems have comprehensive modern terminal applications that ship with the SSH suite installed. Most git hosting providers offer guides on how to create an SSH Key. The SSH command line tool suite includes a keygen tool. SSH keys are created using a key generation tool. This is a one-way formula that ensures the public key can be derived from the private key but the private key cannot be derived from the public key. At a very high level SSH keys are generated through a mathematical formula that takes 2 prime numbers and a random seed variable to output the public and private key. SSH keys are generated through a public key cryptographic algorithm, the most common being RSA or DSA. This data is then opened with the 'private' key which you hold in a secure place. You give the public 'lock' to remote parties to encrypt or 'lock' data. It is more helpful to think of the public key as a "lock" and the private key as the "key". The private vs public nomenclature can be confusing as they are both called keys. The key pair contains a public and private key. SSH uses a pair of keys to initiate a secure handshake between remote parties. The SSH acronym is also used to describe a set of tools used to interact with the SSH protocol. SSH is used for remote file transfer, network management, and remote operating system access. This authenticated and encrypted secure network protocol is used for remote communication between machines on an unsecured open network. An SSH key is an access credential for the SSH (secure shell) network protocol.
