Question: ❓❓❓


Is there any way to get git to give you a commit log for just commits that touched a particular line in a file?

Like git blame, but git blame will show you the LAST commit that touched a particular line.

I’d really like to get a similar log of, not the list of commits to anywhere in the file, but just the commits that touched a particular line.


Good Answer: 👌👌👌

See also Git: discover which commits ever touched a range of lines.


Since Git 1.8.4, git log has -L to view the evolution of a range of lines.

For example, suppose you look at git blame‘s output. Here -L150,+11 means “only look at the lines 150 to 150+11”:

$ git blame -L150,+11 -- git-web--browse.sh
a180055a git-web--browse.sh (Giuseppe Bilotta 2010-12-03 17:47:36 +0100 150)            die "The browser $browser is not

5d6491c7 git-browse-help.sh (Christian Couder 2007-12-02 06:07:55 +0100 157)    vers=$(expr "$($browser_path -version)" 
5d6491c7 git-browse-help.sh (Christian Couder 2007-12-02 06:07:55 +0100 158)    NEWTAB='-new-tab'
5d6491c7 git-browse-help.sh (Christian Couder 2007-12-02 06:07:55 +0100 159)    test "$vers" -lt 2 && NEWTAB=''

And you want to know the history of what is now line 155.

Then, use git log. Here, -L 155,155:git-web--browse.sh means “trace the evolution of lines 155 to 155 in the file named git-web--browse.sh“.

$ git log --pretty=short -u -L 155,155:git-web--browse.sh
