Variables

var ExecCommand = exec.Command

ExecCommand defines how to execute os commands

Types

type Command

type Command struct {
	ErrorCategoryMapping map[string][]string
	// contains filtered or unexported fields
}

Command defines the information required for executing a call to any executable

func (*Command) AppendEnv

func (c *Command) AppendEnv(env []string)

AppendEnv appends environment variables to be used for execution

func (*Command) GetExitCode

func (c *Command) GetExitCode() int

GetExitCode allows to retrieve the exit code of a command execution

func (*Command) RunExecutable

func (c *Command) RunExecutable(executable string, params ...string) error

RunExecutable runs the specified executable with parameters !! While the cmd.Env is applied during command execution, it is NOT involved when the actual executable is resolved.

Thus the executable needs to be on the PATH of the current process and it is not sufficient to alter the PATH on cmd.Env.

func (*Command) RunExecutableInBackground

func (c *Command) RunExecutableInBackground(executable string, params ...string) (Execution, error)

RunExecutableInBackground runs the specified executable with parameters in the background non blocking !! While the cmd.Env is applied during command execution, it is NOT involved when the actual executable is resolved.

Thus the executable needs to be on the PATH of the current process and it is not sufficient to alter the PATH on cmd.Env.

func (*Command) RunShell

func (c *Command) RunShell(shell, script string) error

RunShell runs the specified command on the shell

func (*Command) SetDir

func (c *Command) SetDir(dir string)

SetDir sets the working directory for the execution

func (*Command) SetEnv

func (c *Command) SetEnv(env []string)

SetEnv sets explicit environment variables to be used for execution

func (*Command) Stderr

func (c *Command) Stderr(stderr io.Writer)

Stderr ..

func (*Command) Stdout

func (c *Command) Stdout(stdout io.Writer)

Stdout ..

type ExecRunner

type ExecRunner interface {
	RunExecutable(executable string, params ...string) error
	RunExecutableInBackground(executable string, params ...string) (Execution, error)
	// contains filtered or unexported methods
}

ExecRunner mock for intercepting calls to executables

type Execution

type Execution interface {
	Kill() error
	Wait() error
}

Execution references a background process which is started by RunExecutableInBackground

type ShellRunner

type ShellRunner interface {
	RunShell(shell string, command string) error
	// contains filtered or unexported methods
}

ShellRunner mock for intercepting shell calls
