pyenv/bin/ruby-local-exec

#!/usr/bin/env bash
#
# `ruby-local-exec` is a drop-in replacement for the standard Ruby
# shebang line:
#
#    #!/usr/bin/env ruby-local-exec
#
# Use it for scripts inside a project with an `.rbenv-version`
# file. When you run the scripts, they'll use the project-specified
# Ruby version, regardless of what directory they're run from. Useful
# for e.g. running project tasks in cron scripts without needing to
# `cd` into the project first.
