CLI script to copy a file to the user's public DropBox folder and put a shortened public link in the clipboard. Inspired by @matthewmccullough and @tlberglund

dbshare.sh

#! /usr/bin/env bash

# $1 file to share

db_home=$HOME/DropBox  # You need to run the DropBox client on your workstation
db_id=<999999>         #Put your Dropbox ID here

if [[ -f "$1" ]] ; then

  cp "$1" $db_home/Public   #Only works if you have an Old Style account with magic Public directory

  curl https://www.googleapis.com/urlshortener/v1/url \
    -H 'Content-Type: application/json' \
    -d '{"longUrl": "https://dl.dropboxusercontent.com/u/'$db_id/$(echo "${1##*/}"|  gsed -e 's/ /%20/g')'"}' 2>/dev/null |
  gsed -ne 's/^ *"id": "\([^"]\+\)".*$/\1/p' |pbcopy

  echo $(pbpaste)
else
  echo no valid source file "$1" found
fi

This works for me. If you have problems let me know
