JUNOS is cool

Firstly I know Juniper with JUNOS, I learn more 'JUNOS', I don't believe JUNOS based on Unix. Every time I typing command in management CLI, it's like in Unix machine but I think Juniper make CLI like Unix not based on Unix. After I reading a book about JUNOS Software Architecture. 'The JUNOS software is based on the FreBSD Unix operating system' and I try some command like 'match' and 'trim' wow it's cool. 'match' is not strange like grep / include in other platform OS. Try 'trim', it's like text manipulation in programming language.
