Comment (by eschnett):

 You don't need a subshell for this, a subprocess is good enough. Any time
 you call system() or popen(), there will automatically be a subprocess
 created; whether the executed command is wrapped in a shell or not does
 not matter. That is, the example I gave above is good enough -- there is
 no need to explicitly call a shell.
