# Find The Date That A File Was Added To The Repo
|
|
|
|
The `git log` command has a bunch of flags that you can use to filter
|
|
commits and format their output.
|
|
|
|
We can get `git log` to only show the date for a commit in the `short`
|
|
format with the following flags:
|
|
|
|
```bash
|
|
$ git log --pretty=format:"%ad" --date=short
|
|
```
|
|
|
|
We can also get `git log` to filter commits to just those that have files
|
|
being added:
|
|
|
|
```bash
|
|
$ git log --diff-filter=A
|
|
```
|
|
|
|
Like many `git` commands, we can restrict the output to those that match a
|
|
path or file.
|
|
|
|
```bash
|
|
$ git log -- README.md
|
|
```
|
|
|
|
If we put all of these together, then we have a one-line command for getting
|
|
the date a specific file was added to the repository:
|
|
|
|
```bash
|
|
$ git log --pretty=format:"%ad" --date=short --diff-filter=A -- README.md
|
|
2015-02-06
|
|
```
|
|
|
|
See `man git-log` for more details.
