# Summary: Set or show the global Ruby version
#
# Usage: rbenv global <version>
#
# Sets the global Ruby version. You can override the global version at
# any time by setting a directory-specific version with `rbenv local'
# or by setting the `RBENV_VERSION' environment variable.
#
# <version> should be a string matching a Ruby version known to rbenv.
# The special version string `system' will use your default system Ruby.
# Run `rbenv versions' for a list of available Ruby versions.
set -e
[ -n "$RBENV_DEBUG" ] && set -x
# Provide rbenv completions
if [ "$1" = "--complete" ]; then
