Cmd extends the exec.Cmd struct with convenience functions for reading piped output.

func Command

Command returns the GinCmd struct to execute the named program with the given arguments.

func (*Cmd) Output

func (cmd *Cmd) Output() ([]byte, error)

Output runs the command and returns its standard output.

func (*Cmd) OutputError

func (cmd *Cmd) OutputError() ([]byte, []byte, error)

OutputError runs the command and returns the standard output and standard error as two byte slices.

type Error

type Error struct {
	// The error that was returned by the underlying system or API call
	UError string
	// The function where the error originated
	Origin string
	// Human-readable description of error and conditions
	Description string
}

Error is used to return errors caused by web requests, API calls, or system calls. It implements the error built-in interface. The Error() method returns the Description unless it is not set, in which case it returns the Underlying Error (UError) message.
