How many arguments does each echo command see in this script? Explain.
What will be an ideal response?
The first echo sees a single argument. Even though there are eight words
separated by SPACEs and a NEWLINE, echo’s argument is quoted, causing the
SPACEs and NEWLINE to lose their special meanings to the shell, which passes
the argument to echo. The second echo sees eight arguments, separated
by whitespace, because its argument is not quoted.
