CompTIA PenTest+ PT0-003 Question # 69 Topic 7 Discussion

The syntax (1..254) is incorrect in Bash, as it uses brace expansion or seq for looping. The correct syntax should be:

for i in $(seq 1 254)

Also, the missing do is an issue, but the syntax error mentioned points specifically to the loop structure. Fixing the sequence format resolves it.

Corrected script:

#!/bin/bash

for i in $(seq 1 254); do

ping -c1 192.168.1.$i

done

From the CompTIA PenTest+ PT0-003 Official Study Guide (Chapter 4 – Scanning & Enumeration):

“Bash scripting is commonly used for automation in enumeration. The 'seq' command generates a sequence of numbers for iteration in loops.”
