+
+# `abspath` Function
+
+`abspath` takes a string containing a filesystem path and converts it
+to an absolute path. That is, if the path is not absolute, it will be joined
+with the current working directory.
+
+Referring directly to filesystem paths in resource arguments may cause
+spurious diffs if the same configuration is applied from multiple systems or on
+different host operating systems. We recommend using filesystem paths only
+for transient values, such as the argument to [`file`](/language/functions/file) (where
+only the contents are then stored) or in `connection` and `provisioner` blocks.
+
+## Examples
+
+```
+> abspath(path.root)
+/home/user/some/terraform/root
+```
