You should get api key in your CloudFlare's profile. In "API Keys" section find "View" button near the "Global API Key label".

./escflare <add|create|update> <subdomain>.<domain.name> <iface|ip> [ttl]

Examples:

# vailiy.pupkin.ru - domain name with subdomain(s)
# wan0 - network interface name (you can also use IP address instead)
./escflare update vasiliy.pupkin.ru wan0

# Subdomains can be divided by comma. You can use * for wildcard and @ for root record. If some record is not exists, it will be created. 
./escflare 'vasiliy,*,@,ivan,sergey.pupkin.ru' 123.234.123.234 14400

• At first run script will ask you for all needed variables such as email, key, default tty and will save them inside itself.

• It will not update record again with the same content and ttl. You can force updating with the same data by setting variable forcedupdate with sone nonempty value.

You can get all parameters and values by running:

./escflare <list|ls|show>

./escflare <clean|clear> all

./escflare set llevel

Also you can change it temporary by setting ll environment value:
