Git is much more than just
pull of your code. In this post I will discuss other supporting commands and tricks to handle some scenarios I have encountered while coding in a team. These are also the questions that I'm asked by most git beginners I work with.
I will assume that you already know the
pull and branching concepts of git. Please let me know in comments/DM if you are not and I will create a post on the same.
1. Branch switching is forcing me to commit my changes to the current branch before the checkout. But I don't want to commit my changes yet. What should I do?
If so, you can stash (store them safely aside) your current changes and navigate to the other branch easily.
$ git stash
It will NOT stash the newly added files. Generally the newly added files won't cause any issue while switching to another branch. But still if you don't want to see the newly added files in changes after a branch switch, you can stash them too by adding
-U parameter to the command above.
$ git stash -U
Thenafter, whenever you want your changes back, run:
$ git stash pop
$ git reset --hard
To remove the untracked files and directories [added on 26th Oct 2018]
$ git clean -d -f
First just take a backup of what you committed in a new branch so that you won't lose your changes, using:
$ git checkout -b new-branch-name
It will checkout everything you have in
master branch to
new-branch-name. Next, we need to remove unnecessary commits (hence the changes) from the
You will first need to see the log and get the git commit hash to where you want your
master branch to go back. Think of it like undo.
$ git log commit be6bf5e001852e57bbc2c4e14054e3e539b6601c (HEAD -> master) Author: Sanket Patel <email@example.com> Date: Wed Sep 12 18:19:24 2018 +0530 another commit by mistake commit f7169231dc4b729c97f69a877487cf2ddae54133 Author: Sanket Patel <firstname.lastname@example.org> Date: Wed Sep 12 18:18:56 2018 +0530 commit by mistake commit 9f6deced44efecb59f6d70283b8d0ba2d0a57550 <-- We want to restore at this point Author: Sanket Patel <email@example.com> Date: Wed Sep 12 18:18:26 2018 +0530 good commit
git log --pretty=oneline) you can get rid of additional details and display each commit in single line.
Let's say we are good upto the commit titled good commit i.e.
9f6deced44efecb59f6d70283b8d0ba2d0a57550 and we want to remove the other 2 commits added afterwards. We can do this by:
$ git reset --hard 9f6deced44efecb59f6d70283b8d0ba2d0a57550
It will remove the commits and changes made by mistake in Local.
As explained above in #3, we should first backup and discard commits from local. Our first thought can be, can't just git push simply sync the discard operation we did in local. No, instead the local is now behind than the remote. If you will run
git push, it will throw an error and will ask to first
git pull. So we will have to forcefully instruct remote to accept our push and discard all additional changes the remote have.
⚠️ CAUTION: Before forcefully pushing the code, one should make sure that there is no commit in the remote branch that we want to keep(not want to discard). It is recommended that you do this operation only after communicating with other team members if they are also working in the same branch.
$ git push origin +my-branch
+ to the branch name will forcefully push your changes. That also means, it will discard the commits you discarded in local.
$ git merge others-branch-name --no-commit --no-ff
This tries to merge the changes from
others-branch-name to your branch, but won't commit. So that you will get a chance to review what your branch would look like if the merge happened. You can review and the commit the merge manually.
$ git mv old-name new-name
And if you want to change the case of the existing directory name, you will have to swap them using the temporary directory, as below:
$ git mv DirectoryName temp $ git mv temp directory-name
Happy gitting! :)
