Usage

$ github-subdomains -h

Usage of github-subdomains:
  -d string
    	domain you are looking for (required)
  -e	extended mode, also look for <dummy>example.<tld>
  -k	exit the program when all tokens have been disabled
  -o string
    	output file, default: <domain>.txt
  -raw
    	raw output
  -t string
    	github token (required), can be:
    	  • a single token
    	  • a list of tokens separated by comma
    	  • a file (.tokens) containing 1 token per line
    	if the options is not provided, the environment variable GITHUB_TOKEN is readed, it can be:
    	  • a single token
    	  • a list of tokens separated by comma

If you want to use multiple tokens, you better create a .tokens file in the executable directory with 1 token per line

token1
token2
...

or use an environment variable with tokens separated by comma:

export GITHUB_TOKEN=token1,token2...

Tokens are disabled when GitHub raises a rate limit alert, however they are re-enable 1mn later. You can disable that feature by using the option -k.
