cmd/link Command Line Interface

The go command and any other Go-aware build systems invoke cmd/link
to link a collection of packages into a single binary. By default, cmd/link will
present the same interface it does today:

	cmd/link main.a

produces a file named a.out, even if cmd/link does so by invoking the host
linker in external linking mode.

	c_ISREG  = 0100000 // Regular file
	c_ISLNK  = 0120000 // Symbolic link
	c_ISBLK  = 060000  // Block special file
	c_ISCHR  = 020000  // Character special file
	c_ISSOCK = 0140000 // Socket
)

// FileInfoHeader creates a partially-populated [Header] from fi.
// If fi describes a symlink, FileInfoHeader records link as the link target.
// If fi describes a directory, a slash is appended to the name.
//

	fmt.Printf("%s\n", bytes.Replace([]byte("oink oink oink"), []byte("k"), []byte("ky"), 2))
	fmt.Printf("%s\n", bytes.Replace([]byte("oink oink oink"), []byte("oink"), []byte("moo"), -1))
	// Output:
	// oinky oinky oink
	// moo moo moo
}

func ExampleReplaceAll() {
	fmt.Printf("%s\n", bytes.ReplaceAll([]byte("oink oink oink"), []byte("oink"), []byte("moo")))
	// Output:
	// moo moo moo
}

	}
}
