git reset Example
git reset command
It is used to delete the recent commits ( Like last commit or last 2 commits etc.) and with the help of this command's options, you can reset the state of commits to untracked or stage area.
Prerequisite:- You already have a local git repo where you are working
Consider a new file get created under your repo let's call it tmp.java
Step1: - Create a tmp.java file and check the git status
touch tmp.java
git status
Step 2:- Add tmp.java file to stage area and commit it
git add tmp.java
git commit -m "tmp.java file is added"
Step 3:- Verify the commit
git log --oneline
for example below line shows the commit id for me
ce15b05 (HEAD -> master) tmp.java file is added
Step 4:- Delete last commit with git reset --mixed option ( this is the default option), it will reset the commit to an untracked area means tmp.java file will be in the untracked state.
git reset HEAD~1
Step 5:- Verify the last commit is deleted and the tmp.java file is in the untracked area.
git log --oneline
git status
Now let's use git reset --soft option
Step 6:- Add tmp.java file again to the stage area and commit it
git add tmp.java
git commit -m "tmp.java file is added again"
Step 7:- The log entry should show the last commit
git log --oneline
Step 8:- Delete last commit with git reset --soft option, which moves tmp.java file into the stage area.
git reset --soft HEAD~1
Step 9:- Verify commit is deleted and tmp.java file is in the stage area.
git log --oneline
git status
Now let's use git reset with --hard option
Step 10:- First add a commit for tmp.java file.
git commit -m "tmp.java file is added one more time"
git status
git log --oneline
Step 11:- Delete the commit with git reset --hard option (You need to be sure to use this option because it will permanently delete commit changes). tmp.java file should be permanently deleted.
git reset --hard HEAD~1
Step 12:- Verify that commit is deleted and it deletes the tmp.java files.
git log --oneline
git status
ls
