I used to think the terminal was just that black window that hackers used in movies. I’d open it, type ls, stare blankly at the output, and close it like I’d just entered a room I had no business being in.
Fast forward to now — I live in the terminal. I write scripts that scan networks, exploit vulnerabilities, automate boring tasks, and sometimes, accidentally shut things down (yes, I’ve wiped /var without a backup — we’ve all been there). But one thing I’ve learned the hard way:
If you know your way around the shell, you’re dangerous — in the best possible way.
This is my journey through ethical hacking, DevSecOps, and shell scripting — told from behind the prompt.
👣 ** It All Started With a Ping...**
Before Metasploit, before Burp Suite, before CI/CD pipelines, there was ping. That was my first real "hack." I pinged my own IP. Then my router. Then my friend’s router. That curiosity led me to:
nmap — to scan everything that breathed on the network.
nc — to open mysterious ports and send weird messages.
bash — to stitch it all together in a script that made me feel like a god.
Truth is, the shell gave me control. Not just over machines — over knowledge. Over processes. Over my own impatience.
🔥** Ethical Hacking: Shell or Be Shelled**
If you've ever landed a reverse shell during a pentest, you know the adrenaline. But getting shell access is just the start. What you do next is what separates script kiddies from real operators.
Some real-life lessons:
A client left an SSH private key in a world-readable directory. Guess what I used to find it? find / -type f -name "*.pem" 2>/dev/null
During a red team engagement, I had nothing but a low-priv shell. But a quick uname -a and a Google search later — boom, kernel exploit.
Once, I got in through a misconfigured cronjob. A simple shell script with malicious payload ran every 5 minutes. Set and forget.
Hackers don’t always need exploits. Sometimes, all you need is a working shell and some patience.
🛡️ DevSecOps: When Scripting Becomes Security
We love talking about shifting left, building secure pipelines, and “baking in” security. But 90% of the work? It's bash.
Need to check for open ports before deploying a container? Write a script.
Want to automate secret rotation? Write a script.
Need to block IPs after too many failed logins? Script it. Log it. Push it.
In my current setup, I’ve got scripts that:
Run daily scans with lynis and email me diffs.
Check container base images for vulnerabilities using trivy.
Auto-kill instances with outbound traffic to shady IPs. (True story — saved us once.)
And guess what? It all started in the shell.
⚙️ Favorite One-Liners (and Screw-Ups)
Let’s keep it real — half the stuff I do now came from trial, error, and Reddit. Some favorites I keep in my toolbox:
⛏️ Quick privilege check
find / -perm -4000 2>/dev/null
🐚 Stabilize a shell like a pro
python3 -c 'import pty; pty.spawn("/bin/bash")'
💣 Wipe a directory without confirmation (don’t use this unless you're sure)
rm -rf /var/log/*
And of course:
❌** Accidentally locked myself out of SSH**
chmod 000 /etc/ssh/sshd_config — rookie mistake. Recovery was not fun.
💡** Why the Shell Still Matters in 2025**
We’re surrounded by fancy tools — IDEs, dashboards, UIs. But when those fail, it’s the shell that remains.
Got a production issue at 3AM? You’re SSHing in, not clicking buttons.
Trying to analyze logs for a DDoS attack? awk, grep, cut, sort.
Running a CTF? You’re not winning without shell-fu.
🎯** Final Words from One Addict to Another**
If you’re just getting into hacking, DevOps, or scripting, don’t underestimate the terminal. It might look boring, but it’s a superpower. And once you fall in love with it, there’s no going back.
The shell doesn’t lie. It doesn’t sugarcoat. It just does what you tell it to — for better or worse.
So yeah. Where there’s a shell, there’s a way. And for me, there’s no other way
