Domain Reporter (drep.sh)

drep.sh is a Bash script that checks one or more domain names and outputs a machine-readable report including:

• DNS availability
• HTTP and HTTPS response status
• HTTPS certificate details (subject, issuer, email)
• WHOIS information (registrar, status, registration/creation date)

The output is formatted as CSV for easy parsing.

Installation

1. Make sure you have the required tools installed:

   sudo apt update
   sudo apt install -y curl jq openssl whois dnsutils
   

2. Clone or copy the script to your local machine:

   git clone git@forgejo.parcifal.dev/drep.git
   cd drep
   

3. Make the script executable:

   chmod +x drep.sh
   

Usage

Run the script with one or more domain names as arguments:

./drep.sh stackoverflow.com gaston-lagaffe.be

Example output (CSV):

domain,dns available,http status,https status,https subject,https issuer,https email,whois registrar,whois status,whois registered
stackoverflow.com,<yes>,<redirect https://stackoverflow.com/questions>,<other>,stackoverflow.com,US; Let's Encrypt; E7,<n/a>,<n/a>,<n/a>,<n/a>
gaston-lagaffe.be,<no>,<n/a>,<n/a>,<n/a>,<n/a>,<n/a>,<n/a>,AVAILABLE,<n/a>

Example output, formatted as a table:

domain	dns available	http status	https status	https subject	https issuer	https email	whois registrar	whois status	whois registered
stackoverflow.com	<yes>	<redirect https://stackoverflow.com/questions>	<other>	stackoverflow.com	US; Let's Encrypt; E7	<n/a>	<n/a>	<n/a>	<n/a>

• Redirect URLs are included in the CSV output.
• Fields without data are marked <n/a>.
• The script is designed for Linux environments with Bash.
