# Then add the classes your want to migrate in the klasses array below.
# Then run rake paperclip_migration:migrate_to_s3
# Should work but this is untested and may need some tweaking - but it did the job for me.

# This is a short collection of tools that are useful for managing your
# known_hosts file. In this case, I'm using the '-f' flag to specify the
# global known_hosts file because I'll be adding many deploy users on this
# system. Simply omit the -f flag to operate on ~/.ssh/known_hosts

# Add entry for host
ssh-keyscan -H github.com >> /etc/ssh/ssh_known_hosts

# Scan known hosts
ssh-keygen -f /etc/ssh/ssh_known_hosts -F github.com
