+# Last Commit A File Appeared In
+
+In my project, I have a `README.md` file that I haven't modified in a while.
+I'd like to take a look at the last commit that modified it. The `git log`
+command can be used here with few arguments to narrow it down.
+
+```
+$ git log -1 -- README.md
+commit 6da76838549a43aa578604f8d0eee7f6dbf44168
+Author: jbranchaud <jbranchaud@gmail.com>

+
+    Add some documentation on configuring basic auth.
+```
+
+This same command will even work for files that have been deleted if you
+know the path and name of the file in question. For instance, I used to have
+an `ideas.md` file and I'd like to find the commit that removed it.
+
+```
+$ git log -1 -- docs/ideas.md
+commit 0bb1d80ea8123dd12c305394e61ae27bdb706434

+
+    Remove the ideas doc, it isn't needed anymore.
+```
