You can set Git to preview all of the changes in your commit when you write your commit message. I find this to be a big help in writing my commits (and reminds me to keep the changes in my commits small).
By default Vim is the editor used when writing a Git commit message. While I love Vim, it does work very differently than most other editors. A good option for those who are not comfortable with Vim, is to use a different editor. This is how to setup Git to use a different editor.
By default the output of ‘git log’ is not nearly as useful as it could be. By creating a new command ‘git lg’ that uses some of the options available to ‘git log’, we create a much more useful command.
