davail is a command line utility for easily determining domain name availability.

Run gem install davail.

davail [options...] names...

    -h, --help                       Display this help and exit
    -v, --version                    Display version and exit

    -a, --all-tlds                   Check all TLDs

    -b, --blink-available            Blink when available

    -e, --detailed-errors            Detailed error messages

Place a YAML file at ~/.davailrc, e.g.:

data_format: '%e %b %Y'
queried_tlds: [org com lol codes]
result_delimiter: "  "

Only tested with Ruby 2.2.0, 2.2.2, and 2.2.3.

• Tests are missing.
• Specific domains can’t be looked up like davail foo.com bar.net.
• Lookups are not asynchronous.
• Proper config options documentation is missing.
• Everything shouldn’t be in bin.
• That whole rescue Interrupt thing is hopefully superfluous.
