commit https://github.com/vim/vim/commit/2cab0e191055a8145ccd46cd52869fbb9798b971 Author: Bram Moolenaar <Bram@vim.org> Date: Thu Nov 24 15:09:07 2016 +0100 patch 8.0.0096 Problem: When the input or output is not a tty Vim appears to hang. Solution: Add the --ttyfail argument. Also add the "ttyin" and "ttyout" features to be able to check in Vim script.

#!/bin/sh

# Start GUI Vim on a copy of the tutor file.

# Usage: gvimtutor [xx]
# See vimtutor for usage.

exec `dirname $0`/vimtutor -g "$@"
