About which session are you talking now? A ssh-agent session determined
by SSH_AGENT_PID and SSH_AUTH_SOCKET ?
Add this to your .bashrc or .zshrc:
reuseSSHAgent () {
local f=~/.current-ssh-agent
. $f || true
ps -p "$SSH_AGENT_PID" &> /dev/null || {
ssh-agent | grep -v echo > $f
. $f
ssh-add
}
}
reuseSSHAgent
If there is a ssh agent running it will be used if not it will be
started. Then ssh-add will be run (I use only one key so this is
comfortable to me ..)
Maybe I should check that the socket file exists then I would'nt have to
run ps.
Gentoo has a nice script called "keychain" which provides this and more
for ssh-agent and the gnu-gpg agent. However I felt it was too bloated
and replaced it by this function.
You really don't want to type your password twice, do you ? :)
