+# Show All Commits For A File Beyond Renaming
+
+By including `-- <filename>` with a `git log` command, we can list all the
+commits for a file. The following is an example of such a command with some
+formatting and file names.
+
+```bash
+> git log --name-only --pretty=format:%H -- README.md
+4e57c5d46637286731dc7fbb1e16330f1f3b2b7c
+README.md
+
+56955ff027f02b57212476e142a97ce2b7e60efe
+README.md
+
+5abdc5106529dd246450b381f621fa1b05808830
+README.md
+```
+
+What we may not realize though, is that we are missing out on a commit in
+this file's history. At one point, this file was renamed. The command above
+wasn't able to capture that.
+
+Using the `--follow` flag with a file name, we can list all commits for a
+file beyond renaming.
+
+```bash
+> git log --name-only --pretty=format:%H --follow README.md
+4e57c5d46637286731dc7fbb1e16330f1f3b2b7c
+README.md
+
+56955ff027f02b57212476e142a97ce2b7e60efe

+README.md
+
+ea885f458b0d525f673623f2440de9556954c0c9
+README.rdoc
+```
+
+This command roped in a commit from when `README.md` used to be called
+`README.rdoc`. If you want to know about the *full* history of a file, this
+is the way to go.
