I need to make a POST request via Curl from the command line. Data for this request is located in a file. I know that via PUT this could be done with the --upload-file option.

curl host:port/post-file -H "Content-Type: text/xml" --data "contents_of_file"

You're looking for the --data-binary argument:

curl -i -X POST host:port/post-file \
  -H "Content-Type: text/xml" \
  --data-binary "@path/to/file"

In the example above, -i prints out all the headers so that you can see what's going on, and -X POST makes it explicit that this is a post. Both of these can be safely omitted without changing the behaviour on the wire. The path to the file needs to be preceded by an @ symbol, so curl knows to read from a file.
