This is a really cool tip that I came across that allows you to perform OSX Spotlight search from the Mac Terminal. Add following to your .bashrc or .zshrc on the Mac to do Spotlight-indexed searches from the command line.
function spotlight() {
mdfind "kMDItemDisplayName == '$@'wc";
}
Example
~ spotlight main.py
[/Users/hakim] /Users/hakim/main.py
