In installed WP-CLI v1.5.0
wp --info and it return the correct info.
I then ran
wp user session destroy user1 --all and got this:
CORRECT>w user session destroy prvweb -all (y|n|e|a)?
What might I be doing wrong?
Sounds like you're using
CORRECT, see http://zsh.sourceforge.net/Intro/intro_16.html.
You should be able to use
unsetopt correct to disable that completely or
nocorrect wp ... to disable it for just that command.
