+# rsync-auto
+
+**Command: `vagrant rsync-auto`**
+
+This command watches all local directories of anj
+[rsync synced folders](/v2/synced-folders/rsync.html) and automatically
+initiates an rsync transfer when changes are detected. This command does
+not exit until an interrupt is received.
+
+The change detection is optimized to use platform-specific APIs to listen
+for filesystem changes, and does not simply poll the directory.
