Does Git use diffs?
This is a common misconception around git. But Git does not internally store diffs for each commit, it creates a snapshot of the files during each commit. This means that if you create a file in one commit and modify the same file in second commit, Git will have 2 snapshots for the same file.
Does Git diff show new files?
The git diff command displays the differences between files in two commits or between a commit and your current repository. You can see what text has been added to, removed from, and changed in a file. By default, the git diff command displays any uncommitted changes to your repository.
What is the command to check diff in Git?
git diff –cached [filename] // compare the index with local repository. You can also compare files between two different commits. Every commit in Git has a commit id which you can get when you give git log. Then you can use the commit id if diff command like this.
Where are git commits stored?
.git/objects/ directory
Each object is stored in the . git/objects/ directory, either as a loose object (one per file) or as one of many objects stored efficiently in a pack file.
How does git store diffs?
When you commit, git stores snapshots of the entire file, it does not store diffs from the previous commit. As a repository grows, the object count grows exponentially and clearly it becomes inefficient to store the data as loose object files. Hence, git packs them and stores them as a . pack file.
How do I know if my differential is staged?
If you want to see what you’ve staged that will go into your next commit, you can use git diff –staged. This command compares your staged changes to your last commit. The command compares what is in your working directory with what is in your staging area.
What is A and B in git diff?
As mentioned in the diff man page, a/ et b/ represent the prefix to differentiate source and destination. Actually, you have the options: –no-prefix. Do not show any source or destination prefix. –src-prefix= Show the given source prefix instead of “a/”.
