100% rollback files to a specific revision

Test load balancers
With the "--resolve" switch, you can avoid doing DNS lookups or edit the /etc/hosts file, by providing the IP address for a domain directly. Useful if you have many servers with different IP addresses behind a load balancer. Of course, you would loop it: $ for IP in 10.11.0.{1..10}; do curl --resolve subdomain.example.com:80:$IP subdomain.example.com -I -s; done

Report full partitions from a cron
Reports all local partitions having more than 90% usage. Just add it in a crontab and you'll get a mail when a disk is full. (sending mail to the root user must work for that)

Send data securly over the net.
Using OpenSSL we can encrypt any input we wish and then use Netcat to create a socket which can be connected to from an externally source (even using a Web Browser)
