With a PC, I always felt limited by the software available. On Unix, I am limited only by my knowledge.
– Peter J. Schoenster

If you have any trouble sounding condescending, find a Unix user to show you how it's done.
– Scott Adams

How do I type “for i in *.dvi; do xdvi $i; done” in a GUI?

Unix gives you just enough rope to hang yourself – and then a couple of more feet, just to be sure.
– Eric Allman

Unix is user-friendly. It's just very selective about who its friends are.
– Unknown

There are two major products that came out of Berkeley: LSD and UNIX. We don't believe this to be a coincidence.
– Jeremy S. Anderson

“unzip; strip; touch; finger; mount; fsck; more; yes; umount; sleep” - my daily unix command list

Unix is simple. It just takes a genius to understand its simplicity.
– Dennis Ritchie

UNIX was not designed to stop its users from doing stupid things, as that would also stop them from doing clever things.
– Doug Gwyn

A good magician never reveals his secret; the unbelievable trick becomes simple and obvious once it is explained. So too with UNIX.
– Unknown

Beaten paths are for beaten men.
– Unix Shell Programming

That's what I love about GUIs: They make simple tasks easier, and complex tasks impossible.
– John William Chambless

Sigh. I like to think it's just the Linux people who want to be on the “leading edge” so bad they walk right off the precipice.
– Craig E. Groeschel

Those who do not understand UNIX are condemned to reinvent it, poorly.
– Henry Spencer

UNIX is like sex: If you don't know it, you don't miss is. But if you know it, you'll need it.
– Lars Eilebrecht

We know Linux is the best, it can do infinite loops in five seconds.
– Linus Torvalds

In retrospect, we can see that the ideas within Unix served as the basis of modern operating system design. Still, I suspect that the original Unix programmers did not fully understand the significance of what they had invented; for Unix is nothing less than a way of thinking: a modern implementation of the nucleus of human creativity.
– Harley Hahn

Live with Unix long enough and you will change. You will become more creative, and you will come to understand the spirit of creation in others.
– Harley Hahn

More than any other computer system today, Unix will repay every moment that you spend learning and experimenting.
– Harley Hahn

Unix is easy to use, but difficult to learn. Unix is a set of tools for smart people.
– Harley Hahn

Unix has retarded OS research by 10 years and Linux has retarded it by 20.
– Dennis Ritchie

I remarked to Dennis [Ritchie] that easily half the code I was writing in Multics was error recovery code. He said, “We left all that stuff out [of Unix]. If there’s an error, we have this routine called panic, and when it is called, the machine crashes, and you holler down the hall, ‘Hey, reboot it.’”
– Tom Van Vleck

Unix never says 'please'.
– Rob Pike
