From df3ab67a699d2bc4e46a8c2aea4fd95b9df66172 Mon Sep 17 00:00:00 2001 From: Hardy Date: Tue, 10 Sep 2019 17:57:31 +0800 Subject: [PATCH] Add a example for union operator in the shell env MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In the current example, single quotes are used, but the union operator can be confusing.
