Introduction

Linux isn’t just an operating system—it’s a superpower. Once you get comfortable with the terminal, you realize how much faster, cleaner, and more efficient tasks become. The right commands don’t just save time; they give you a sense of control over your machine.

If you’re a beginner or someone curious about leveling up, this guide covers 10 Linux commands that will make you feel like a true power user. Let’s dive in.


1. Navigating Like a Pro

Most people know cd and ls, but a few extra tricks turn these basics into power tools.

     • cd & pwd

        ◦ cd lets you move around directories. Try cd - to jump back to the last folder instantly.

        ◦ pwd shows your current path—handy when you’re buried deep in directories.

    • ls -lah

        ◦ Instead of plain ls, use ls -lah to see file permissions, ownership, hidden files, and human-readable sizes.

        ◦ Example:

                          ls -lah

          Output shows hidden .files, permissions like rwx, and file sizes in KB/MB.

    • tree

        ◦ Visualize directory structures in a neat tree-like format.

        ◦ Install it with:

                      sudo apt install tree

        ◦ Then run tree inside a directory to see its hierarchy.


2. System Monitoring & Control

Want to keep an eye on your system like a hacker in the movies? These commands make it easy.

    • htop

        ◦ A colorful, interactive system monitor that shows CPU, memory, and processes.

        ◦ Start it with:

                          htop

        ◦ Use arrow keys to navigate and F9 to kill a process.

    • du -h & df -h

        ◦ du -h shows disk usage of files and folders (great for cleaning up space).

        ◦ df -h shows available disk space across mounted drives.

        ◦ Example:

                          du -h --max-depth=1

                          df -h

    • kill & killall

        ◦ Sometimes apps freeze. Use kill <PID> to stop a specific process.

        ◦ Use killall <appname> to stop all instances of an app.

        ◦ Example:

                          killall firefox


3. File Power Moves

Power users know how to bend files to their will. These commands unlock serious flexibility.

    • grep

        ◦ Search inside files for specific text or patterns.

        ◦ Example:

                      grep "error" /var/log/syslog

        ◦ Perfect for hunting down logs or config details.

    • find

        ◦ Search for files anywhere in the system.

        ◦ Example:

                      find /home -name "*.txt"

        ◦ This finds all .txt files under /home.

    • tar & gzip

        ◦ Compress and extract files like a pro.

        ◦ Example: Create an archive:

                      tar -czvf backup.tar.gz /home/user/Documents

        ◦ Extract an archive:

                      tar -xzvf backup.tar.gz


4. Networking & Connectivity Tricks (Bonus)

When things go wrong with Wi-Fi or servers, these tools save the day.

    • curl

        ◦ Fetch data from websites or APIs directly from the terminal.

        ◦ Example:

                      curl https://example.com

    • ping & traceroute

        ◦ ping checks if a server is reachable.

        ◦ traceroute shows the path packets take to reach a destination.

        ◦ Example:

                      ping google.com

                      traceroute google.com

    • ssh

        ◦ Connect securely to a remote machine.

        ◦ Example:

                # Basic SSH Usage

                        ssh user@192.168.1.10


            # Logging in as root (not recommended for security reasons)

                        ssh root@192.168.1.10


            # Connecting with a specific port (e.g., port 2222)

                        ssh -p 2222 user@192.168.1.10


            # Using an identity/private key for authentication

                        ssh -i ~/.ssh/id_rsa user@192.168.1.10


            # Enabling verbose mode for troubleshooting

                        ssh -v user@192.168.1.10
