Git Stash

This little blog post is just for me to remember my favorite "git stash" commands. It took me a little while to actually use the stash, but that is because IntelliJ provides a similar functionality called "shelving", which I had used all this time.

I use branches a lot when using Git, and the problem there is that Git usually complains if I wish to change branches, while I still have uncommitted changes in my current branch. Therefore the "stash" command is for me very valuable.

Stash your current uncommitted changes:
$ git stash

Get your uncommitted changes back from the stash:
$ git stash apply

Get a list of your current stashes:
$ git stash list
stash@{0}: WIP on master: 049d078 added the index file
stash@{1}: WIP on master: c264051 Revert "added file_size"
stash@{2}: WIP on master: 21d80a5 added number to log
Remove a no longer needed stash:
$ git stash drop stash@{0}
Dropped stash@{0} (364e91f3f268f0900bc3ee613f9f733e82aaed43)
One command I particularly like is this one that does both an apply of your stash and once done automatically removes it from the list of stashes:
git stash pop

The stash has a lot of similarities to your standard Stack implementation (or Dequeue, depending on your point of view.)

I notice that if I do not clean up the place or use the "pop" subcommand, that my list of stashes tends to grow quite long unobtrusively.
