As I find that UpperCase are really readable for first letter word separation in long complex names, I tend to give some of my linux files names with some UpperCase. Mostly executables, some directories too.

But it's been a few weeks I have remarked that the huge majority off all file names in my linux distrib are lowercase...

So I made some googling a moment ago, and I found this page, that states one should always use lowercase in the unix world.

Is that really the case ???
