You are writing a Bash script that loops through a list of hosts, calls a scanning utility, and appends the results to a single file. Which approach meets these objectives in a repeatable manner?
Create a function that prompts for each address and merges results in memory for later display.
Use a for statement that runs the utility on each address, appending the output each time.
Use a while statement that reads each address, runs the utility, and overwrites the output file with each iteration.
Call the scanning utility once against all addresses at once, writing results to separate files.
A for statement can iterate over each target, sending the scanner’s output to a single file using the append operator. This method consolidates all results without overwriting existing data. A while statement with overwrite would remove prior output. Calling one scanning utility invocation with multiple addresses may break host-by-host documentation. A prompt-based function loses the streamlined nature of a loop and risks overwriting prior results in memory.
