UNIX is a licensed copyrighted Trademarked OS that is proprietorially were as Gnu/Linux are licensed for free use with free software.

Slackware is a UNIX-like Gnu/Linux;

excerpt from Slackware General Info;
The Slackware Philosophy

Since its first beta release in April of 1993, the Slackware Linux Project has aimed at producing the most "UNIX-like" Linux distribution out there. Slackware complies with the published Linux standards, such as the Linux File System Standard. We have always considered simplicity and stability paramount, and as a result Slackware has become one of the most popular, stable, and friendly distributions available.

Freebsd is UNIX-like;

Quote:

excerpt from Freebsd wiki;
FreeBSD is a free Unix-like operating system descended from AT&T UNIX via BSD UNIX. Although for legal reasons FreeBSD cannot be called “UNIX”,[1] as the direct descendant of BSD UNIX (many of whose original developers became FreeBSD developers), FreeBSD’s internals and system APIs are UNIX-compliant. Thanks to its permissive licensing terms, much of FreeBSD’s code base has become an integral part of other operating systems such as Mac OS X that have subsequently been certified as UNIX-compliant and have formally received UNIX branding.[2] With the exception of the proprietary Mac OS X, FreeBSD is the most widely used BSD-derived operating system in terms of number of installed computers, and is the most widely used freely licensed, open-source BSD distribution, accounting for more than three quarters of all installed systems running free, open-source BSD derivatives.[3]
FreeBSD is a complete operating system; the kernel, device drivers, and all of the userland utilities, such as the shell, are held in the same source code revision tracking tree.[4] (This is in contrast to Linux distributions, for which the kernel, userland utilities, and applications are developed separately, and then packaged together in various ways by others.) Third-party application software may be installed using various software installation systems, the two most common being source installation and package installation, both of which use the FreeBSD Ports system.

HTH!
