From 3bd2f3dc81469a6a7f31a7096677fc11ed06ed30 Mon Sep 17 00:00:00 2001 From: Markus Heiser Date: Tue, 27 Apr 2021 13:02:55 +0200 Subject: [PATCH] [fix] manage - fix miss usage of 'set -e' MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The philosophy of set -e is typically that it only exits upon uncaught errors. Here, the presence of || outside the subshell seems to tell the shell that the error inside the subshell is 'caught' and therefore set -e does not cause an exit after false [1]. The shell does not exit if the command that fails is ... part of any command executed in a && or || list except the command following the final && or ||, any command in a pipeline but the last, or if the command’s return status is being inverted with !
