Why is '-e' required? The -e tells 'echo' to "-e enable interpretation of
backslash escapes", but there are no backslash escapes in the output of the
'fdisk -l' to worry about.
What's important is that you have the double quotes around the variable
expansion, which preserves all white space characters 'as is' (or if you
prefer, as they were in the original fdisk output - tabs, spaces and newlines).
The entire content of the variable is passed to echo as a single (very large;)
argument with embedded white space characters intact.
Without the double quotes, echo sees multiple arguments. The arguments were
created by the shell, using the white space separators to break them up. echo
never sees any white space, so it it prints each argument separated from the
next by a single space, which puts everything together into one long,
unformatted string.
