QUESTION: When the code below is run, what will be output to the terminal?#!/bin/bashstr='Book Title 1: <em>Think and Grow Rich</em> by Napoleon Hill'echo $str | sed 's/.*>.∗<.*/\1/'exit 0Group of answer choices<em></em>hink and Grow Ricby Napoleon HillThink and Grow Rich

The code you provided is a bash script that uses the sed command to manipulate a string. However, the regular expression used in the sed command is incorrect, so it will not work as expected.

The sed command is supposed to replace the string that matches the regular expression with \1, which refers to the first captured group in the regular expression. However, there are no parentheses in the regular expression to define a captured group, so \1 doesn't refer to anything.

Moreover, the regular expression .*>.∗<.* is supposed to match any string that contains > and <, but the . before > and the . after < are not correct. They should be .* to match any characters.

If you want to extract the book title "Think and Grow Rich" from the string, you can use the following bash script:

#!/bin/bash
str='Book Title 1: <em>Think and Grow Rich</em> by Napoleon Hill'
echo $str | sed 's/.*<em>\(.*\)<\/em>.*/\1/'
exit 0

In this script, the regular expression <em>\(.*\)<\/em> matches the string that is enclosed in <em> and </em>, and (.*?) captures the book title. The sed command replaces the whole string with the captured book title, so "Think and Grow Rich" will be output to the terminal.
