I try not to use this blog to flog my employer's products but I just used the open source "Google Command Line" program and I have to spread the word... this really rocked.
I wanted to upload a bunch of photos to Picasa. I didn't want to sit there clicking on the web interface to upload each one, I didn't want to import them into iPhoto and then use the Picasa plug-in to upload them. I just wanted to get them uploaded.
Google CL to the rescue! It is a program that lets you access many google properties from the command line. It works on Mac, Linux and Windows. After a (rather simple) install process I was ready to give it a try.
Here's the command line that I typed:
$ google picasa create --title "2010-08-09-Hobart-Tasmania-SAGE-AU" ~/Desktop/PHOTOS-AU/*
I was expecting it to ask me for a username and password but I was surprised when it my web browser popped up, asked me to authorize this script to have permission to log in (just like third-party apps that authenticate against Google), and when I was back at the command line I pressed "return" to continue. The upload began and finished a few minutes later.
In addition to picasa, the command can also access blogger, youtube, docs, contacts and calendar.
