You're developing a Bash script that reads lines from a text file. If a line contains the word "error," the script should display an error message and continue reading the next line. If a line contains the word "success," it should display a success message and break out of the loop. For all other lines, it should display a generic message. Which code snippet correctly implements this behavior using a while loop?1.0 Markswhile read -r line; doif [[ "$line" == *"error"* ]]; thenecho "Error: $line"elif [[ "$line" == *"success"* ]]; thenecho "Success: $line"breakelseecho "Info: $line"fidone < file.txtwhile IFS= read -r line; doif [[ "$line" =~ "error" ]]; thenecho "Error: $line"elif [[ "$line" =~ "success" ]]; thenecho "Success: $line"breakelseecho "Info: $line"fidone < file.txtwhile read -r line; doif [[ "$line" =~ "error" ]]; thenecho "Error: $line"elif [[ "$line" =~ "success" ]]; thenecho "Success: $line"breakelseecho "Info: $line"fidone < file.txtwhile IFS= read -r line; doif [[ "$line" == *error* ]]; thenecho "Error: $line"elif [[ "$line" == *success* ]]; thenecho "Success: $line"breakelseecho "Info: $line"fidone < file.txtPowered by Fedena

You're developing a Bash script that processes a list of numbers stored in a file. The script should calculate the sum of all numbers in the file. If any of the numbers are negative, it should display an error message and exit. Which code snippet correctly implements this behavior using a while loop?1.0 Markssum=0while read -r number; doif [[ "$number" -lt 0 ]]; thenecho "Error: Negative number detected."exit 1fi((sum += number))done < numbers.txtecho "Sum: $sum"sum=0while read number; doif [ $number -lt 0 ]; thenecho "Error: Negative number detected."exit 1fisum=$((sum + number))done < numbers.txtecho "Sum: $sum"sum=0while IFS= read -r number; doif [ "$number" -lt 0 ]; thenecho "Error: Negative number detected."exit 1fisum=$((sum + number))done < numbers.txtecho "Sum: $sum"sum=0while read -r number; doif [ "$number" -lt 0 ]; thenecho "Error: Negative number detected."exit 1fi((sum += number))done < numbers.txtecho "Sum: $sum"sum=0while read -r number; doif ((number < 0)); thenecho "Error: Negative number detected."exit 1fisum=$((sum + number))done < numbers.txtecho "Sum: $sum"

Given the following script code:1   Sort Stations.txt > SortCount.txt2   echo "The number of words in the file:" >> SortCount.txt3   cat Stations.txt | wc -w >> SortCount.txt4   echo "The number of line in the file:" >> SortCount.txt5   cat Stations.txt | wc -l >> SortCount.txtWhich line of code will cause error when running the script? Assume that file Stations.txt exists and is accessible.Group of answer choicesLine 5There is no error in the scriptLine 3Line 1

Sometimes it is convenient to break out of a while loop from within the body of the while loop itself. This is often the case when it is more sensible to test a condition in the body that is different from the while loop condition.A typical case iswhile condition_for_doing: <some_code> if condition_for_breaking: break <more_code>If condition_for_breaking is satisfied then <more_code> is skipped:>>> x = 0>>> while x < 10:... print(f"Before {x}")... if x > 1:... break... print(f"After {x}")... x = x + 1... print(f"Done {x}")Before 0After 0Before 1After 1Before 2Done 2Note that breaking in the middle of a while loop is generally considered bad programming practice because it often leads to bugs which are difficult to resolve.Breaking from at the end of a loop to simulate a do-while loop is fine.TaskWrite a program that uses a while loop to repeatedly prompt the user for numbers until the user enters nothing (empty string). Print the average of the numbers entered.You must use a break statement to exit the while loop in order to credit for this question.

You are developing a Bash script that needs to run a command repeatedly until it succeeds. Which loop construct is the most appropriate choice for this task, considering both efficiency and error handling?1.0 Marksuntil [ $? -eq 0 ]; do command; donewhile [ $? -ne 0 ]; do command; donefor i in {1..5}; do command && break; donewhile true; do command && break; donefor ((i=0; i<5; i++)); do command || break; done
