Types

type CommandExecutor

type CommandExecutor struct {
}

CommandExecutor is the type of the Executor

func (*CommandExecutor) ExecuteCommand

func (c *CommandExecutor) ExecuteCommand(command string, arg ...string) error

ExecuteCommand starts a process and wait for its completion

func (*CommandExecutor) ExecuteCommandResidentBinary

func (*CommandExecutor) ExecuteCommandResidentBinary(timeout time.Duration, command string, arg ...string) error

func (*CommandExecutor) ExecuteCommandWithCombinedOutput

func (*CommandExecutor) ExecuteCommandWithCombinedOutput(command string, arg ...string) (string, error)

ExecuteCommandWithCombinedOutput executes a command with combined output

func (*CommandExecutor) ExecuteCommandWithEnv

func (*CommandExecutor) ExecuteCommandWithEnv(env []string, command string, arg ...string) error

ExecuteCommandWithEnv starts a process with env variables and wait for its completion

func (*CommandExecutor) ExecuteCommandWithOutput

func (*CommandExecutor) ExecuteCommandWithOutput(command string, arg ...string) (string, error)

ExecuteCommandWithOutput executes a command with output

func (*CommandExecutor) ExecuteCommandWithOutputFile

func (*CommandExecutor) ExecuteCommandWithOutputFile(command, outfileArg string, arg ...string) (string, error)

ExecuteCommandWithOutputFile executes a command with output on a file #nosec G307 Calling defer to close the file without checking the error return is not a risk for a simple file open and close

func (*CommandExecutor) ExecuteCommandWithOutputFileTimeout

func (*CommandExecutor) ExecuteCommandWithOutputFileTimeout(timeout time.Duration,
	command, outfileArg string, arg ...string) (string, error)

ExecuteCommandWithOutputFileTimeout Same as ExecuteCommandWithOutputFile but with a timeout limit. #nosec G307 Calling defer to close the file without checking the error return is not a risk for a simple file open and close

func (*CommandExecutor) ExecuteCommandWithTimeout

func (*CommandExecutor) ExecuteCommandWithTimeout(timeout time.Duration, command string, arg ...string) (string, error)

ExecuteCommandWithTimeout starts a process and wait for its completion with timeout.

type Executor

type Executor interface {
	ExecuteCommand(command string, arg ...string) error
	ExecuteCommandWithEnv(env []string, command string, arg ...string) error
	ExecuteCommandWithOutput(command string, arg ...string) (string, error)
	ExecuteCommandWithCombinedOutput(command string, arg ...string) (string, error)
	ExecuteCommandWithOutputFile(command, outfileArg string, arg ...string) (string, error)
	ExecuteCommandWithOutputFileTimeout(timeout time.Duration, command, outfileArg string, arg ...string) (string, error)
	ExecuteCommandWithTimeout(timeout time.Duration, command string, arg ...string) (string, error)
	ExecuteCommandResidentBinary(timeout time.Duration, command string, arg ...string) error
}

Executor is the main interface for all the exec commands
