Git tip: switch to previous branch

You can use git switch - to switch to the previous branch. In the following example, we see switching back and forth between branches main and my_dev_branch:

    
C:\git\my-repo [my_dev_branch]> git switch -
Switched to branch 'main'
Your branch is up to date with 'origin/main'.
C:\git\my-repo [main ≡]> git switch -
Switched to branch 'my_dev_branch'
C:\git\my-repo [my_dev_branch]>

Edit: Old habits die hard. Updated to use switch instead of checkout since switch has a clearer responsibility. Obviously they work exactly the same for this scenario.

Which follows the similar functionality used by the cd - command to switch to the previous directory you were in. Very handy!
- You can do what 👀
  
  There's more! Well, it's more a bash thing than a cd thing.. in bash the variable $_ refers to the last argument to the previous command. So you can do the following:
  
  > mkdir -p my/nested/dir > cd $_ > pwd /home/user/my/nested/dir
  It's handy for a whole host of things, like piping/touching then opening a file, chown then chmod, etc.
  
  There's also pushd and popd so that you can pushd into one directory, move around as much as you want and then go back to before the pushd with popd
- … how have I not ever come across that before?!
  This thread has been invaluable for me lol
Use switch, boomer!
- Old habits die hard. Thanks for pointing this out. I updated the post.
  
  Oh lol, I was just trying to poke fun, sorry if it came across as accusatory. 😎👍
- NEVER!!
- What's the difference? Genuine question
  
  Checkout was one of those commands that I joking would call Turing complete because of how much you can do with it (I haven't actually tried to see if it is, but am fully prepared for someone to be nerd sniped and tell me it actually is). I think they're mostly the same, but switch and restore were added as more straightforward versions of checkout and reset.
  
  Well one starts with an s, the other with a c... :P
  They changed the command to clarify what it does, checkout was / is used for switching branches as well as branch creation but has connotations of doing some locking in the repo from older vcs software.... I think. the new commands are switch and branch. check the docs
  Idk what the deal is with switch, I thought it wasn't supposed to be creating branches but right in the docs there's a flag for it???
  Im the kind of user that just deletes .git and starts over when I f up the repo, so take my git advice with a tablespoon of salt.
Great tip!! Thanks!
That's so cool, this can be my favorite command so on. Switching between two branches is easy with that.
Note that git checkout - / git switch - examine reflog to find previous branch. Which means if you renamed the branch, at least current version of Git would be unable to run git switch -.
But evidently git rev-parse - will not print out the previous branch 😔 that would have been useful for scripts
This led me down a real rabbit hole of looking at what you can do with git commands, very neat.
There's a few more things you can do which I found, like switching to the Nth branch you last had checked out: https://www.w3docs.com/snippets/git/how-to-checkout-the-previous-branch.html
