Subject: [PATCH 6/9] lei_overview: do not write if $lei->{1} is gone
Date: Tue, 19 Jan 2021 09:34:32 +0000	[thread overview]
Message-ID: <20210119093435.17955-7-e@80x24.org> (raw)
In-Reply-To: <20210119093435.17955-1-e@80x24.org>

We'll invalidate the {1} (stdout) field on SIGPIPE,
so don't trigger a Perl warning by writing to it.
