CentOS 8 RPMs

It looks like CentOS 8 EPEL does not yet have a ShellCheck RPM:

FROM centos:8

RUN yum install -y epel-release && \
yum install -y ShellCheck

It is a shame! Afraid I don't know how to build it myself, but apparently if you ask nicely someone might do it. Maybe on Bugzilla?

In the mean time I made this script to securely install it on Centos, let me know if you find any problems:

curl -Of https://shellcheck.storage.googleapis.com/shellcheck-v0.7.0.linux.x86_64.tar.xz
