+
+# TL;DR
+
+If you want to show the name of the latest tag, use:
+
+    git for-each-ref --sort=-taggerdate --count=1 --format '%(tag)' refs/tags
+
+# Some background
+
+The command *git for-each-ref* is pretty useful if you want to find something
+in a number of commits (or tags in this case). It allows you to use variations of
+output and sorting methods. For example:
+
+### Show all tags including the message
+
+    git for-each-ref --format '%(refname) %(contents:subject)' refs/tags
+
+(this is btw. very similar to **git tag -n1**)
+
+### Show all tags sorted by date, oldest first
+
+    git for-each-ref --sort=taggerdate --format '%(refname)' refs/tags
+
+### Show all tags sorted by date, newest first
+
+    git for-each-ref --sort=-taggerdate --format '%(refname)' refs/tags
+
+### Show latest two tags
+
+    git for-each-ref --count=2 --sort=-taggerdate --format '%(refname)' refs/tags
+
+### Show latest tag with its non-ambiguous short name
+
+    git for-each-ref --sort=-taggerdate --count=1 --format '%(refname:short)' refs/tags
+
+### Show latest tag
+
+    git for-each-ref --count=1 --sort=-taggerdate --format '%(tag)' refs/tags 
+
+(note: this is the same as the previous one, but uses the *tag* field)
