Subject: [alpine-user] Executing shell command produces nothing on Alpine linux
To: alpine-user@lists.alpinelinux.org
Content-Type: multipart/alternative; boundary="001a113db50266df010550c4ef82"

I am running shell commands inside my Perl script, but it does not work as
expected. I am in a container with Alpine Linux as my base image.

my Perl version v5.24.0.

perl -e 'my $TEST = `ls -al`; print $TEST'

This prints nothing, but works on another system where I have Perl v5.6.1
on Red Hat Linux.
