Other than fork and exec, it is not possible to make a system while avoiding the shell. Would be nice to have this, similar to perl's system:

and python's subprocess:

The reason to avoid the shell is security. From python's own documentation

We already have a bunch of extra options for system() so I'm proposing to implement something like perl, and skip the shell if the first argument is a cell array of strings. Does that sound good?
