Functions

func ParseCommand

func ParseCommand(s *settings.Settings, raw string) (command []string, name string, err error)

ParseCommand parses the command taking in account if the current instance uses a shell to run the commands or just calls the binary directly.

func SplitCommandAndArgs

func SplitCommandAndArgs(command string) (cmd string, args []string, err error)

SplitCommandAndArgs takes a command string and parses it shell-style into the command and its separate arguments.

Example

var commandLine string
var command string
var args []string

// just for the test - change GOOS and reset it at the end of the test
runtimeGoos = osWindows
defer func() {
	runtimeGoos = runtime.GOOS
}()

commandLine = `mkdir /P "C:\Program Files"`
command, args, _ = SplitCommandAndArgs(commandLine)

fmt.Printf("Windows: %s: %s [%s]\n", commandLine, command, strings.Join(args, ","))

// set GOOS to linux
runtimeGoos = osLinux

commandLine = `mkdir -p /path/with\ space`
command, args, _ = SplitCommandAndArgs(commandLine)

fmt.Printf("Linux: %s: %s [%s]\n", commandLine, command, strings.Join(args, ","))

Output:
Windows: mkdir /P "C:\Program Files": mkdir [/P,C:\Program Files]
Linux: mkdir -p /path/with\ space: mkdir [-p,/path/with space]
