From 240c015ac6ea629bef1339ed2829148051c2a954 Mon Sep 17 00:00:00 2001 From: Ryan Moeller Date: Thu, 5 Sep 2019 12:51:59 -0400 Subject: [PATCH] Refactor checksum operations in tests md5sum in particular but also sha256sum to a lesser extent is used in several areas of the test suite for computing checksums. The vast majority of invocations are followed by `| awk '{ print $1 }'`. Introduce functions to wrap up `md5sum $file | awk '{ print $1 }'` and likewise for sha256sum. These also serve as a convenient interface for alternative implementations on other platforms.
