What Is GF Tool?

GF tool scans files for hidden secrets like passwords or keys. It works like a detective. You give it files, and it finds sensitive data. It’s perfect for bug hunting or security checks.

Why Use GF Tool in Kali Linux?

Kali Linux is packed with hacking tools. Adding GF makes it even stronger. It’s fast, simple, and saves time. Plus, it’s free and open-source.

Before You Start

Check if your Kali Linux is updated. Open the terminal and run:

sudo apt update && sudo apt upgrade -y  


You’ll also need Go programming language. GF is built with Go. Don’t worry—we’ll install Go next.


Step 1: Install Go in Kali Linux
First, install Go. Type this command:

sudo apt install golang -y  


Wait for the installation to finish. Go helps run GF smoothly.

Step 2: Set Up Go Environment
Next, set the Go path. Open your bash profile:

nano ~/.bashrc  


Add these lines at the end:

export GOPATH=$HOME/go  
export PATH=$PATH:$GOPATH/bin  


Save the file (Ctrl+O, then Ctrl+X). Reload the settings:

source ~/.bashrc  

Step 3: Install GF Tool
Now, install GF using Go:

go install github.com/tomnomnom/gf@latest  


This command downloads GF from GitHub.

Step 4: Set Up GF Patterns
GF needs pattern files to work. Create a folder and copy patterns:

mkdir -p ~/.gf  
git clone https://github.com/tomnomnom/gf && cp -r gf/examples ~/.gf  


Now GF knows what secrets to look for.

Step 5: Test GF Installation
Check if GF works. Type:

gf -help  


If you see a list of commands, you’re done!


Customizing GF for Better Results

You can add your own patterns to GF. Edit files in the ~/.gf folder. For example, create aws-key.json to search for AWS keys.

Fixing Common GF Errors

  • GF command not found: Check your Go path. Re-run source ~/.bashrc.
  • Patterns missing: Re-clone the GF repo and copy the examples folder again.
  • Permission issues: Use sudo before commands or check folder permissions.
