Re-tag, since the task is text-processing and not restricted to files, and the central issue is not the newline character. Tried to clarify the task description from my interpretation of the OP's self-answer.
Simplest way of stripping leading/trailing whitespace from standard input
- Simplest way of stripping leading/trailing whitespace from file or program output
What is the simplest shell idiom for stripping leading and trailing whitespace from standard output? Ideally I am looking for the equivalent of `trim` or `strip` methods in some languages.There is potentially a confusion here about whether I'm asking about trimming only the first and last lines, or if every line should individually be trimmed. An ideal solution would assume the first, but make the second a CLI switch.

- The ideal solution should
- * skip empty lines at the beginning and end of the file/stream
- * provide an option to also strip leading and trailing whitespace from all non-empty lines
