Current Behavior

https://i3wm.org/docs/ipc.html says:

You can get the socketpath from i3 by calling i3 --get-socketpath.

All i3 utilities, like i3-msg and i3-input will read the I3_SOCKET_PATH X11 property, stored on the X11 root window.

Desired Behavior

The IPC documentation should document that the socketpath can be get using the I3SOCK environment variable, available since #3476.

Note that I3SOCK is documented in i3-input.man, i3-msg.man, i3bar.man, i3.man and docs/userguide.

Impact

[ ] This feature requires new configuration and/or commands

Environment

Output of i3 --moreversion 2>&-:
