Function newInteractiveShellCmd

pkg/tui/handlers.go:908–923

newInteractiveShellCmd returns a command that launches the user's preferred interactive shell. The command is owned by tea.ExecProcess, not by any request-scoped context, so exec.Command is intentional.

(exitMsg string)

// interactive shell. The command is owned by tea.ExecProcess, not by any
// request-scoped context, so exec.Command is intentional.
func newInteractiveShellCmd(exitMsg string) *exec.Cmd {
	if goruntime.GOOS != "windows" {
		shell := shellpath.DetectUnixShell()
		return execCmd(shell, "-i", "-c", `echo -e "\n`+exitMsg+`"; exec `+shell)
	}

	psArgs := []string{"-NoLogo", "-NoExit", "-Command", `Write-Host ""; Write-Host "` + exitMsg + `"`}
	if path, err := exec.LookPath("pwsh.exe"); err == nil {
		return execCmd(path, psArgs...)
	}
	if path, err := exec.LookPath("powershell.exe"); err == nil {
		return execCmd(path, psArgs...)
	}
	// Use absolute path to cmd.exe to prevent PATH hijacking (CWE-426).
	return execCmd(shellpath.WindowsCmdExe(), "/K", "echo. & echo "+exitMsg)
}

// execCmd is a thin wrapper around exec.Command used for interactive
// processes whose lifecycle is owned by tea.ExecProcess (not a context).
