Investigate the areas where UNIX® and Linux® converge in terms of functionality, environment, usability, and also those areas where UNIX and Linux differ.

It is an open source operating system that has many of the same principles and ideals as UNIX, but it is not a true UNIX operating system like Solaris, AIX®, HP-UX, and others. This article covers a range of aspects, from the core technical elements, such as kernel and filesystem support, to application tools, availability, and the differences in how to administer them.
