HIGHLIGHT TOOLS FOR TERMINAL

highlight is a script designed to highlight specific patterns in log files or text streams using ANSI escape codes for colorization. It can detect and highlight patterns such as URLs, domains, IPv4 addresses, IPv6 addresses, subnets, ports, categories, HTML tags, and more.

Features

• Highlights URLs (http, https, ftp, ftps, sftp, ssh, telnet, file, git), both with and without www
• Recognizes and highlights domains with and without ports.
• Highlights IPv4 addresses and subnet masks.
• Detects and highlights IPv6 addresses.
• Highlights ports (e.g., 80/tcp, 443/udp).
• Recognizes and highlights categories or labels followed by a colon (:).
• Identifies and highlights HTML tags and their attributes.
• Highlights text within parentheses ((...)).
• Colorizes text within double quotes ("...").

Installation

1. Clone the repository:

git clone https://github.com/ReconXSecurityHQ/highlight.git
 cd highlight

2. Run setup and reload the source script:

chmod +x setup
./setup
source ~/.bashrc

in case you encounter this:

$ ./setup
-bash: ./setup: cannot execute: required file not found

just try to run this and reload the source

dos2unix setup; ./setup

Usage

Once installed, use the highlight command followed by the file name or pipe input from another command.

examples

Highlight patterns in a log/text file:

highlight < access.log

Highlight patterns in nmap scan results:

sudo nmap -sV -sC -Pn hackerone.com | highlight

Highlight IP addresses in ifconfig output:

ifconfig | highlight

Highlight URLs in curl output:

curl -s -i https://www.hackerone.com | highlight

Customization

You can customize or extend the script by modifying the highlight function defined within highlight.sh. This function uses awk to match and replace patterns with ANSI escape sequences for colorization. Each pattern is matched using regular expressions tailored to its specific format (URLs, IP addresses, domains, etc.).

To add or modify patterns:

• Edit the highlight function inside highlight.sh.
• Adjust or add gsub commands to match new patterns or change existing highlighting behavior.

Notes

• Ensure your terminal emulator supports ANSI escape codes for proper color rendering.
• Modify the script according to your specific needs or additional highlighting patterns.
