Why Linux is not fully safe:

Misconfiguration → If you use weak passwords, leave SSH open, or run everything as root, hackers can get in.

Exploits → New vulnerabilities are discovered regularly (kernel, software packages, web servers).

Social engineering → Hackers may trick you into installing malicious software or running bad commands.

Targeted attacks → If you’re running a server (like websites, databases, etc.), attackers will try to break in.

Outdated software → Old Linux distributions without updates are very unsafe.

# Step 1: Load FileAbuo into a set (fast lookups)
with open(file_abuo, 'r') as f2:

# Step 2: Process FileOfu line by line and keep only unique ones

    for line in f1:
        clean_line = line.strip()

            out.write(clean_line + '\n')
