hi BBOSAK2143
You are free to tinker and play as much as you want with Solaris. In usage there is practically no difference vs linux. There are some commands which are native to it though. Solaris is a highly structured os--- if it aint broken never fix it.
A server os primarily and worked on Sunmicro's ultrasparc chip. Since then Oracle got it on x86_64.
A "elder" sibling of linux with a parentage from unix. Solaris is still strictly unix unlike linux with different and changing standards.
Having used solaris most people and myself would not recommend using linux or any other os on the server but after SunMicro's stint and then giving themselves to Oracle most users and corporations still swore by Solaris on their ultrasparc and x64 servers. But that was then
It is still used today (limited) but is a stagnated field. Most newcomers will jump onto solaris once they hear something about a more rigid unix os that can run on their system but other than a thrill and a "toy" -- everyone gives up.
Best thing to do -- do one thing do it well.
The biggest reason why people give up solaris is for monetary reasons. You just cant earn anything more than bread and butter.
