+# Reveal Location Of File In Finder.app
+
+In the terminal I have the path to an image file. I want to open Finder.app to
+the location of that image file so that I can drag and drop it into a file
+upload area in the browser.
+
+Instead of opening a Finder.app window and navigating directory by directory to
+the location, I can use the `open` command. Using `open` directly with the image
+file will open the image in Preview.app. I want to reveal the directory that the
+image file is in within Finder.app. _Reveal_ is the keyword and the `-R` flag
+does just that.
+
+Here is an example of this that I actually ran when uploading a screenshot that
+went into [this blogmark post](https://still.visualmode.dev/blogmarks/255):
+
+```bash
+$ open -R /Users/lastword/images/tiobe-index-graph-march-2026.png
+```
+
+See `man open` for more details.
