How to extract the Root CA and Subordinate CA from a certificate chain in Linux?

I have an end-entity/server certificate which have an intermediate and root certificate. When I cat on the end-entity certificate, I see only a single BEGIN and END tag. It is the only the end-entity certificate. Is there any way I can view the intermediate and root certificate content. I need only the content of BEGIN and END tag. In Windows I can see the full cert chain from the "Certification Path". Below is the example for the Stack Exchange's certificate. From there I can perform a *View Certificate* and export them. I can do that for both root and intermediate in Windows. I am looking for this same method in Linux.
