ssh-askpass for OSX 10.10

gistfile1.sh

#!/bin/sh

# Save as /usr/libexec/ssh-askpass or somewhere else you control and set the
# SSH_ASKPASS environment variable to the location of this script.
# chmod a+rx /usr/libexec/ssh-askpass or
# chmod +x ~/wherever/you/saved

# NOTE: This is for OS X 10.10 only and shouldn't work on previous OS X. The
# format returned from osascript changed from "text returned:blah, button
# returned:OK" to "button returned:OK, text returned:blah". This script
# simply cuts on the : and returns the third field.
