Subject: [PATCH v4 1/8] t5520: prevent field splitting in content comparisons
Date: Mon, 18 May 2015 21:32:51 +0800	[thread overview]
Message-ID: <1431955978-17890-2-git-send-email-pyokagan@gmail.com> (raw)
In-Reply-To: <1431955978-17890-1-git-send-email-pyokagan@gmail.com>

Many tests in t5520 used the following to test the contents of files:

	test `cat file` = expected

or

	test $(cat file) = expected

These 2 forms, however, will be affected by field splitting and,
depending on the value of $IFS, may be split into multiple arguments,
making the test fail in mysterious ways.

Replace the above 2 forms with:

	test "$(cat file)" = expected

as quoting the command substitution will prevent field splitting.

* Removed use of "verbose"

* The use of "wc -l" is not quoted, as the output of "wc -l" on a Mac contains
  leading whitespace. See [1].
