func AllowError ¶

func CommandOutputOrPanic ¶

func CommandOutputOrPanic(command string, args ...string) string

func Error ¶

func Error(c *exec.Cmd) ([]byte, error)

Error runs the command and returns its standard error.

func GeneratePassword ¶

func GeneratePassword() string

Uses [A-Za-z0-9] characters (default set) to avoid strange escaping problems that could potentially affect security. Prefixed with `pWd0_` to ensure password contains a special character (_), lowercase and uppercase letters, and a number. This is useful if the OS has a strict password policy requiring all of these. The total password length is 29 characters (24 of which are random). 29 characters should not be too long for the OS. The 24 random characters of [A-Za-z0-9] provide (26+26+10)^24 possible permutations (approx 143 bits of randomness). Randomisation is not seeded, so results should not be reproducible.

func ProcessCommandOutput ¶

func ProcessCommandOutput(lineEnding string, callback func(line string), prog string, options ...string) error

func RunCommands ¶

func RunCommands(allowFail bool, commands ...[]string) error
