A command line tool for Hook.app on macOS.
Hook is a great productivity tool for macOS that allows you to create links between your files, emails, websites, and everything in your digital life, no matter where each item exists. For people who spend a lot of time in Terminal, it only makes sense we should have access to Hook’s power from the command line.
To install, just run
gem install hookapp.
If you’re on a stock Ruby install (i.e. have never installed
rbenv), you may need sudo and your system password:
sudo gem install hookapp.

link command always creates bidirectional hooks. Give it two or more files or urls and it will create links between them. By default it links all files to the last file in the list. Add the
--all flag to link all files to every other file in the list. This can be abbreviated as
hook ln -a file1.md file2.pdf "https://brettterpstra.com".
Similar to the way you would use the GUI, you can use
hook clip file1.md to copy a Hook URL to the clipboard, and then use
hook ln -p file2.pdf to create a link from the clipboard to
You can also clone all of the links on one file to another, great for adding a new file to a group that’s fully crosslinked. Just use
hook clone file1.md file2.pdf.
list (aliased as
ls) command to list all attached hooks for a file. With no output format specified,
ls will show the paths to all hooks, or the hook url if the hook doesn’t have a file path (e.g. a URL). You can specify an output format using
--output_format (abbreviated as
-o) with one of “markdown”, “hooks”, “paths”, or “verbose”. Formats can be abbreviated to their first letter, so to display a Markdown list of all hooked files, use
hook ls -o m file1.md.
hook remove file1.md file2.pdf to remove the bidirectional link between
file2.pdf. Add the
--all flag (abbr.
-a) with one or more files to remove ALL the hooks on them. This option requires confirmation.
Super nerdy scripting trick
--output_format=paths option (abbr.
-o p) combined with the
--files_only flag (abbr.
-f) will list just the paths and only include hooks that have file paths (i.e. exclude web, email, and other URLs). This can be combined with
--null to output the list using a NULL separator, perfect for use with
xargs or other command line tools.
Acting on hooks
You can open a hooked file or URL by running
hook select file1.md. This will display a menu of all the hooks on
file1.md, and entering the number of a selection will open that file in its default application.
You can also open a file in the Hook GUI using
hook open file1.md.
