Git: Who has modified this line?

Git

Git Problem Overview

If I found a bug in my application, sometimes I need to know which commits have affected to the bug source code line. I'm wondering which is the best approach to do it with Git.

Git Solutions

Solution 1 - Git

To see commits affecting line 40 of file foo:

git blame -L 40,+1 foo

The +1 means exactly one line. To see changes for lines 40-60, it's:

git blame -L 40,+21 foo

OR

git blame -L 40,60 foo

The second number can be an offset designated with a '+', or a line number. git blame docs

Solution 2 - Git

I'd use the git blame command. That's pretty much exactly what it is for. The documentation should get you started.

Solution 3 - Git

git blame filename

is the best command to show you this info

Solution 4 - Git

If you only need the last change:

git blame

Otherwise, you could try to automatically find the offending change with

git bisect

Solution 5 - Git

You can use

git annotate filename (or)

git blame filename
