From: Đoàn Trần Công Danh Date: Sun, 22 Mar 2020 00:55:19 GMT Subject: [PATCH v2 6/6] t4124: fix test for non-compliance diff Message-ID: In-Reply-To: POSIX's diff(1) requires output in normal diff format. However, busybox's diff's output is written in unified format. POSIX requires no option for normal-diff format. A hint in test-lib-functions::test_cmp said `diff -u` isn't available everywhere. Workaround this problem by assuming `diff(1)` output is unified if we couldn't make anything from normal-diff format.
