# 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 -H -F github.com

If:

- you add and commit with the wrong email address in git, and
- your remote has a hook set up to prevent you from pushing with the bad address

Then you need to amend the author of your commit before push can succeed:

1. fix your email address in git config:

$ git config user.name "Your Name"
