Saturday pronounciation thread

After a suggestion from @gjs, I thought it would be fun to ask how various /prague/riders pronounce those UNIX utilities and programming terms we’ve all read a million times but perhaps not said.

With that, how do you pronounce:

/etc
/lib
char
fsck
schema (and how do you pluralize it?)

ετκ
λιμπ
τσαρ (same for tsar)
φσκ
σκ(χ)έμα, σκ(χ)έμες
