How to retrieve public URL of a file via cmd line?

Question

How can I get the public URL of a file via a command? I need to do this within a Lua script, so Python or whatever else API's are offered aren't any good.

Answer 1

To get a public URL for a file via the commandline, you do

u1sdtool --publish-file=filename

if the file is already published, it will return the existing URL; otherwise, it will publish the file and return the newly created URL.
