Correct Syntax for a Range Loop in Bash:

The seq command generates a sequence of numbers in a specified range, which is ideal for iterating over IP addresses in a Class C subnet (1–254).

Example: seq 1 254 will output numbers 1, 2, ..., 254 sequentially.

Explanation of Other Options:

A (crunch): The crunch command is used for wordlist generation and is unrelated to looping in Bash.

C (echo 1-254): This would output " 1-254 " as a string instead of generating a numeric range.

D ({1.-254}): This is incorrect Bash syntax and would result in a script error.

Final Script:

bash

for var in $(seq 1 254)

do

ping -c 1 192.168.10.$var

done
