I'm not a JS developer, so this as much of a question as it is a statement.

`exec` is a system call and doesn't call bash or any other shell. At least, it shouldn't.

If it does, then it would be wrong to assume that bash is even available.

Either way. The single quote sytax is specific to bash (and maybe sh, dash, etc. I'm not certain.) so, don't rely upon it.
