Handle multiple ssh-agents

gistfile1.sh

# Shell snipet to handle multiple ssh-agents
#
# By default I use an ssh-agent with a lot of keys added with the -c option to
# ssh-add and this agent is forwarded trough most of my connections.
# But for some taske this confirmation step is a hassle, so I create new
# agents without confirmation with a minimal set of keys.
#
# You have to source this "script" to work or use the hack described at
#   http://peter.makholm.net/2009/07/07/shell-hacks-bash-functions-in-files/
