- qs STRING #!optional PLATFORMprocedure
Escapes STRING suitably for passing to a shell command on PLATFORM. PLATFORM defaults to the value of (build-platform) and indicates in which style the argument should be quoted. On Windows systems, the string is simply enclosed in double-quote (") characters, on UNIXish systems, characters that would have a special meaning to the shell are escaped using backslash (\).
