Domainbadger is a fast and simple CLI-tool used to find unregistered domains using wildcards & characterset combinations.

brew install emmanuelay/tap/domainbadger

Example

domainbadger -c aoe -t se,io,nu h_ll_ w_rld d_min_ti_n

This will perform a WHOIS lookup on domain name combinations using selected top-level domains (se, io, and nu) and combinations of the characters aoe in three separate search terms h_ll_, w_rld, and d_min_ti_n. Underscore _ is treated as the wildcard character and is replaced with different combinations of aoe.

h_ll_ contains two wildcard characters, which means domainbadger will combine aoe in all possible combinations using 2 character slots (3 characters in 2 slots can be combined in 3^2 = 9 possible combinations: halla, hallo, halle, etc.).
