Get Time of First Commit of a File

<p> In <a class="wikilink" href="/git/"> git </a> , to get the time of the first commit for every file in a directory, it is enough to run the following: </p> <pre class="codehilite"><code>$ git log --format=format"%ci" --name-only --diff-filter=A </code></pre> <p> Which will produce something like this: </p> <pre class="codehilite"><code>2020-10-03 15:06:25 +0200 content/Dispertech.md content/things I've done.md 2020-10-01 14:57:15 +0200 static/14092.jpg static/Aquiles.jpg static/aquiles_square.jpg static/deardisya.ttf 2020-10-01 12:21:03 +0200 content/digital garden tos.md content/optimization.md content/there is more to data than what meets the eye.md content/what is a machine learning algorithm.md content/why backlinks are the core of my digital garden.md </code></pre> <p> The date and time of the commit and the files that were added. </p> <p> The important parts are: <code> --diff-filter=A </code> will only look at when files are added comparing one commit with the previous one. We can also use <code> D </code> to see deleted files, <code> M </code> for modified, or <code> R </code> for renamed. <a href="https://git-scm.com/docs/diff-options"> The docs </a> explain all the rest of choices. </p> <p> <code> --name-only </code> will output the name of the files, while the <code> --format </code> decides how to output the information. Out of the box, we have these choices: </p> <ul> <li> oneline </li> <li> short </li> <li> medium </li> <li> full </li> <li> fuller </li> <li> reference </li> <li> email </li> <li> raw </li> </ul> <p> Or we can specify our own formatting, by making use of <a href="https://git-scm.com/docs/git-log#_pretty_formats"> pretty formats </a> . Some examples would be: </p> <pre class="codehilite"><code>%ci </code></pre> <p> Commit date </p> <pre class="codehilite"><code>%cn </code></pre> <p> Committer name </p> <pre class="codehilite"><code>%s </code></pre> <p> Commit subject (the message) </p>
