I have multiple ssh-agent's running, but I don't know which one is accessed by my ssh-add command. If with -*extra*l, I could find out, this would be helpful!
this does not belong to the -L or -l option
So what is your suggestion - add a new option?
Or another option would be to have ssh-agent complain if it detects other instances of itself already running under the same userID?
perhaps have ssh-add -v print out the socket name.
sure, would be great if this additional option could be added...
I don't think that making "ssh-add -v" print the socket name would help much - you can do that yourself with "echo $SSH_AUTH_SOCK"
I don't think there's much to be done for this; as djm points out, figuring out which agent ssh-add will access is simply a matter of echoing $SSH_AUTH_SOCK (or $SSH_AGENT_PID for that matter).
Change all RESOLVED bug to CLOSED with the exception of the ones fixed post-4.4.
