Top 50 Linux Commands – Quick Guide for Security & SysAdmin Pros

Linux is the backbone of cybersecurity , servers , and DevOps . Mastering commands makes you faster, sharper, and more effective in troubleshooting , monitoring , and defending systems .

From navigation & file ops (ls, cd, pwd, cp, mv) to permissions & ownership (chmod, chown, umask), Linux gives you total control. For process & system monitoring (ps, top, htop, kill, uptime), you can quickly spot what’s happening inside your machine.

Networking is at the heart of cybersecurity: commands like ifconfig/ip a , ping , traceroute , netstat/ss , and curl/wget help you diagnose and analyze connections. For security researchers , tools like tcpdump , nmap , and wireshark provide deep packet insights.

You’ll also need package & service management (apt-get, yum, systemctl, journalctl), archiving & compression (tar, gzip, zip/unzip), and text processing (grep, awk, sed, sort). Combine them with scripting (bash, cron, alias) to automate and scale your work.

Disclaimer:
For educational purposes only. Use these commands responsibly in labs or on systems you manage.

I only just learned you can use the mouse in the TTY! (The Linux text-only console you get to by pressing Ctrl+Alt+F1, F2, etc.)

Some applications that enable this are gpm and consolation.

consolation worked better for me, especially when in tmux; however, I still can't get scrolling with middle button and trackpoint to work, which is what would be the most useful for me. I don't know if it has to do with consolation, tmux mouse bindings, my particular ThinkPad model, etc. I can't find anything online about this, so if you've also dabbled in this, please share your experience!

A really cool thing I just learned: since version 3.4, Pandoc lets you output markup with ANSI escape codes so you can see formatted text in the terminal!

However, the default formatting (e. g. inline code as red on light grey) kind of makes my eyes bleed?

Here's the commit. Any Pandoc mavens know how to customize the colours? Like do I edit a copy of ANSI.hs and put it…somewhere? Do I make a custom Lua filter? Halp ;_;

I made just another new release of #tablizer with a couple of small fixes: 1.5.3. The most important change is that I switched the demo tool. I am now using vhs by charm, which I love soooo much! See the result attached, very nice.

Oh, joy! Yet another command-line tool that lets you #retry that command you *already* know is going to fail. Because obviously, the solution to bad code is to make it fail faster! Why fix bugs when you can just keep smashing your head against the keyboard with style?
