Hello @vdabhi123

Please make sure that you have installed kube bench sucessfully by following those commands:
curl -L https://github.com/aquasecurity/kube-bench/releases/download/v0.3.1/kube-bench_0.3.1_linux_amd64.tar.gz -o kube-bench_0.3.1_linux_amd64.tar.gz

tar -xvf kube-bench_0.3.1_linux_amd64.tar.gz

then try again to run it using this command:

./kube-bench --config-dir pwd/cfg --config pwd/cfg/config.yaml

I have done those steps and version for kube-bench is 0.4.0.(as per exercise)

But during ./kube-bench - -config-dir pwd /cfg --config pwd /cfg/config.yaml

The issue I highlighted is coming
