Because xxd ignores any trailing newline in the input, echo or echo -n will behave precisely the same here; whether there's a newline by echo makes no difference, because that Decode each line separately (useful for when you have multiple entries). 1), but adding dedicated cmdlets has been suggested in GitHub issue #8620. Multi-line Base64 strings often occur when dealing with larger data. Decode each line separately (useful for when you have multiple entries). Do you really want to take character data, convert it to bytes, then convert it back to character data, this time unreadable and with no hint of what the original Decode a Base64-encoded string; Convert a date and time to a different time zone; splits up the input line by line and runs all subsequent operations on each line separately.
