I want to know the differences between Solaris and linux as they seem to be one and the same in terms of commands.

Wikipedia has a wealth of information on UNIX and UNIX like systems. For example see http://en.wikipedia.org/wiki/Unix and the links within.

Depends on level you are working.. (from a certain angle Windows and Linux looks similar). Because both are Unix like OS and attempt POSIX compliance using and system programming are similar. Just because they support same set of commands doesnt mean they are same (at least the "tar" command isnt). Obviously there are structural differences. This might be eg. pre-emption, scheduling, SMP support, security measures, paging, ASR etc. Again really depends how and why you are using. Some features might be more important than others like support for a particular filesystem or application which again is very different. Bottom line is they are very different operating systems (both internally and externally) with some very interesting similarities.

Solaris is based on the True AT&T source code of their Unix OS. Much like Linux.
