Parsing newline-delimited data records in bash is simple, if you have this odd redirect up your sleeve. An annoying thing about bash is that it usually equates all whitespace characters, so the first block in the snippet won't let you use a file linewise, but will end up echoing each whitespace-delimited token on a separate line.

bash provides the "read" builtin which can be used to differentiate between newlines and spaces.
