Functions

func EchoCommand 

func EchoCommand(w io.Writer, argv []string)

EchoCommand writes the set -x-style echo line "+ <argv>\n" to w.

func ShellJoin 

func ShellJoin(argv []string) string

ShellJoin renders argv as a shell-style command line: elements are joined with single spaces; any element containing whitespace or a single quote is single-quoted (each ' escaped as '\”), bash set -x style. Simple elements pass through unquoted. Empty argv joins to the empty string.

Types

type LockedWriter added in v0.8.0 

type LockedWriter struct {
	W io.Writer
	// contains filtered or unexported fields
}

LockedWriter serializes concurrent writes to W. os/exec spawns one copy goroutine per stream when Stdout and Stderr are different writers, so two MultiWriters capturing into one bytes.Buffer race (and silently lose writes) without it.

func (*LockedWriter) Write added in v0.8.0 

func (l *LockedWriter) Write(p []byte) (int, error)
