I started this blog just around a month ago on a quest to learn more about git on a daily basis and to show others how awesome it is. If you have any suggestions on what content to cover or how things should be done differently, I would greatly appreciate it. Thanks!

Heh, I've already got this in my RSS reader. It's got some pretty awesome tips. I've learned more about git on there than pretty much any other resource.

Keep up the good work. :)

Well done.

One topic that IMHO you fail to cover, and which is being neglected almost everywhere else too, is the reflog.

The reflog is really your safety net when working with git. It records everything you do. So even if you screw up a rebase, perform the wrong merge, or any other kind of undesired operation, then you may always go back to a previous state. Either you use -g with 'git log' to see all those recorded states, or even 'git reflog' without any argument to get a condensed list for HEAD.

The <branch>@{<spec>} notation can be used anywhere a ref is normally required. The special branch "HEAD" shows every state the HEAD pointer went through, including branch switches. The <branch< part can be left out to mean "currently checked-out branch".

One thing that I use all the time after a 'git pull' is 'git log @{1}..' where "@{1}" means the first previous tip of the current branch, so effectively showing me the log of what the pull brought in my branch.

Also, the @{now} notation to get a relative timestamp of the reflog is invaluable. Seeing reflog lines annotated with '14 minutes ago' or '17 hours ago' or perhaps '4 days ago', really helps to focus on the commits you're looking for:

    git reflog show @{now}
    # (the 'show' is not optional in this syntax)

Yes, I often use "git log -g --date=relative" to get a better understanding of my recent actions in that particular repository.

Also do not forget to advertise the new @{-<n>} notation for the n-th last branch you were on (to be part of 1.6.2 AFAIU). This comes in really handy when you juggle a dozen branches (and happen to commit to the wrong branch ;-)

Ciao, Dscho
