Does it really? I've executed it here and it just runs kill, doesn't emit any bash. Running just ssh-agent (without any args) does that though, which is what's probably causing the confusion.
- chasil 3y agoI am on OpenBSD 7.2, and I see: $ eval $(ssh-agent) Agent pid 56785 $ ssh-agent -k unset SSH_AUTH_SOCK; unset SSH_AGENT_PID; echo Agent pid 56785 killed; The correct processing of that output requires an eval. Did you have any other questions?
- pmarreck 3y agoWhy do you need to eval it? $(ssh-agent) won’t substitute that with the stdout and run that?
- chasil 3y agoBecause the intended use for "ssh-agent -k" is for eval. While redirecting to /dev/null will certainly work, the agent is holding sensitive credentials (by design), and confirmation of shutdown has a tangible security benefit.
