Executing Files (without shell)

[thefed]

Once again, a similarly themed question from me:

Is it possible (without syscall ) to execute a file without using a
shell?


Thanks

Calling Kernel#system will sometimes fork a shell if you pass it
something complicated like pipelines, but you can be guaranteed that it
won't spawn a shell (it will execve the binary directly) if you pass the
binary name and the command line arguments as separate parameters. (E.g.
system("echo","hello","world") Likewise if you're running a binary that
takes no parameters so there's only one string being passed as a
parameter.

Guarenteed? Are you certain? I just want to be sure....
