# 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

To set this up, paste the code below into the "location" of a bookmark. Make sure it starts with "javascript:", some browsers strip this out when you paste.

1. Find the "name" of each form element you want to put data into. You can find the "name" by right clicking on the form box and "inspecting" it.
2. By using a spreadsheet, create a set of urls with the data you want to input. Example: variablename1 is the "name" of the form field. "value1" is the value you want to put into the box.www.website.com/page.html?variablename1=value1&variablename2=value23. Navigate to that custom URL4. Click the bookmarklet. Voila!
