Challenge: #NI6

how is both of these supposed to work, I made it so it removes the extra spaces, but the it again supposed to keep the extra spaces.

Can anyone point out what am I missing

Hey @logan1o1

  • Spaces inside quotes should be preserved.
  • If two quoted strings have no space between them, they’re treated as one token.

Expected: "example     hello scriptworld"

Let me know if you’d like further clarification!

Even I had the same doubt that you’re mentioning, and it helped me to realize the more general rule that bash shells follow: end of a quoted string does not necessarily mean end of a token. You should only end a token when you recieve either:

  • A whitespace
  • A tab
  • End of input
    (Goes without say that these should be in an unquoted string and not escaped)

Yeah, solved, it took a while but got it
