Say you have the env variable $SKIP_CI_VERIFICATION. How do you switch on that in your bash script?
There are two basics tests that are relevant: -n and -z
-n tests if "not empty"if [[ -n $SKIP_CI_VERIFICATION ]]; then
echo "it is set"
-z tests the opposite (i.e. if empty)if [[ -z $SKIP_CI_VERIFICATION ]]; then
echo "it is NOT set"
