In order to execute a command on your OS, you need to define it as a Shell method.
Alternatively, you can execute any command via Shell::CommandProcessor#system even if it is not defined.

Base class for all URI exceptions.
Not a URI.
Not a URI component.
URI is valid, bad usage is not.
The default port for HTTPS URIs is 443, and the scheme is ‘https:’ rather than ‘http:’. Other than that, HTTPS URIs are identical to HTTP URIs; see URI::HTTP.
The default port for LDAPS URIs is 636, and the scheme is ‘ldaps:’ rather than ‘ldap:’. Other than that, LDAPS URIs are identical to LDAP URIs; see URI::LDAP.

Protocol error.
Remote host reset the connection request.
Client sent TCP reset (RST) before server has accepted the connection requested by client.
An HTTP response. This is filled in by the service or do_* methods of a WEBrick HTTP Servlet.

Raised when a mathematical function is evaluated outside of its domain of definition.
For example, since cos returns values in the range -1..1, its inverse function acos is only defined on that interval:
Math.acos(42)
produces:
Math::DomainError: Numerical argument is out of domain - "acos"
Process::Status encapsulates the information on the status of a running or terminated system process. The built-in variable $? is either nil or a Process::Status object.
fork { exit 99 } #=> 26557 Process.wait #=> 26557 $?.class #=> Process::Status $?.to_i #=> 25344 $? >> 8 #=> 99 $?.stopped? #=> false $?.exited? #=> true $?.exitstatus #=> 99
Posix systems record information on processes using a 16-bit integer. The lower bits record the process status (stopped, exited, signaled) and the upper bits possibly contain additional information (for example the program’s return code in the case of exited processes). Pre Ruby 1.8, these bits were exposed directly to the Ruby program. Ruby now encapsulates these in a Process::Status object. To maximize compatibility, however, these objects retain a bit-oriented interface. In the descriptions that follow, when we talk about the integer value of stat, we’re referring to this 16 bit value.
Raised by Encoding and String methods when a transcoding operation fails.
Raised by Encoding and String methods when the string being transcoded contains a byte invalid for the either the source or target encoding.
Raised by transcoding methods when a named encoding does not correspond with a known converter.
