This is a tool to start a drag session for a file from the terminal. I found I was often running open . from within a terminal just so I could drag a file to an application, so this was to avoid that.

Compile it with

g++ drag.mm -framework Cocoa -o drag

Then you can move or symlink it to somewhere in your PATH.

Just run:

drag «file»

You can use tildes and relative paths.
