# Show Only Commits That Touch Specific Lines
|
|
|
|
When you run `git log`, you are listing all commits in reverse-chronological
|
|
order for the current branch. There are ways of filtering the commits that
|
|
get output from `git-log`. As of Git 1.8.4, `git-log` output can be filtered
|
|
by commits that touch a range of line numbers.
|
|
|
|
This is done with the `-L` flag.
|
|
|
|
For instance, if I want to see all commits that touched the 13th line of my
|
|
`README.md` file, then I can do this:
|
|
|
|
```bash
|
|
$ git log -L13,13:README.md
|
|
```
|
|
|
|
I can alter the command to show commits that touched a range of lines like
|
|
so:
|
|
|
|
```bash
|
|
$ git log -L19,45:README.md
|
|
```
|
|
|
|
I used the `-L` flag recently to find when a dependency was added to my
|
|
`package.json` file even though the most recent changes to that line were
|
|
version bumps.
