Subject: [PATCH 02/12] check: really improve test list randomization
Date: Tue, 19 Mar 2019 17:44:49 -0700 [thread overview]
Message-ID: <155304268908.31707.9639554348139720057.stgit@magnolia> (raw)
In-Reply-To: <155304267647.31707.14180452399822113095.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
coreutils provides the shuf(1) utility that randomizes the order of a
list and seeds its random number generator with /dev/urandom. It's a
bit speedier than awk, so use it if available.
