How to Filter in GATK4

I'm using GATK version4. After using VariantFiltration, I got the information of "PASS" of "not PASS". Next I want to filter out the "not PASS" variants. So I used the Selectvariants but, I can't filtered out the the not PASS variant well?
Please tell me how to use the -select argument.

Thank you
