I have an update to my [previous article]{screen-ssh-agent} on forwarding [ssh-agent]{tag/ssh}
through [screen]{tag/screen}. I’ve since switched to [zsh]{tag/zsh} and am now forwarding
the X DISPLAY
environment variable through to the screen shell.
You can grab my ~/.zsh.d/S51_screen, ~/.zsh.d/S60_prompt, and ~/.screenrc or read below.
