From 204c7fb2293f67f6277f917e854188f5540e6955 Mon Sep 17 00:00:00 2001 From: Rostislav Skudnov Date: Fri, 16 Sep 2016 19:04:02 +0000 Subject: ash: exit after subshell error when errexit option is set When "set -e" option is on, shell must exit when any command fails, including compound commands of the form (compound-list) executed in a subshell. Bash and dash shells have this behaviour. Also add a corresponding testcase.
