Maybe I am not thinking clearly..

How does tr work? I mean, I tested it, and it clearly works. Maybe I do not understand the arguments for it. The man pages make it seem as though all it will do is replace SET1 with SET2, so how does: tr -sc 'a-zA-Z' '\n' make it just replace () and comas? Seems like it is basically replacing the opposite, (grep -v comes to mind..).

-c, -C, --complement
first complement SET1

-s, --squeeze-repeats
replace each input sequence of a repeated character that is listed in SET1 with a single occurrence of that character
