Interesting, old programs like 'rm' only use lower case but new programs like bash and git (or should I say "Bash" and "Git") capitalize the program name sometimes.
Given that Unix (not "unix") inherited case sensitivity from Multics I would expect more consistency in the spelling.
(Clearly I'm focusing on the most important topics in computing!)
