From 3da3488e6339ff2dc5c7f3da8c8a0c552d018d68 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Wed, 17 Jan 2018 10:17:16 -0800 Subject: [PATCH] Fix shellcheck v0.4.6 warnings Resolve new warnings reported after upgrading to shellcheck version 0.4.6. This patch contains no functional changes. * egrep is non-standard and deprecated. Use grep -E instead. [SC2196] * Check exit code directly with e.g. 'if mycmd;', not indirectly with $?. [SC2181] Suppressed.
