How to find machine module name for `drush dl`? Long time Drupal front-end dev but doing more site building lately and have been using Drush much more. One of the biggest limitations I've found with downloading (dl) command is that you have to know the machine name of the module, which is not a big issue for say Views or Context. But who knows the machine name of stuff like node reference or simple google maps? 

I guess and get it right sometimes, or I have to hit d.o to figure it out. Is there a list function I havent uncovered? The other answers to this on Stack Overflow and Drupal Answers are pretty bad.

drush dl module-name-here
According to my experience, I know machine names of some commonly used modules,
but basically when it is for new module or when I have doubt in machine name, 
I google it the module name, it should provide you with link for drupal project page,

the url will be in the format   https://drupal.org/project/[project-machine-name]

drush dl [project-machine-name]


for multiple module you can do like this 

drush dl [project-machine-name1] [project-machine-name2][project-machine-name2] ..
