Synopsis
exec <string>
The string argument is a command which gets executed as a background process
from the shell.
Note that the exec command is system dependent, and will give different
results on Windows than on a UNIX system. On UNIX systems (eg Linux and
Mac OS X) the process id of the background process is returned as an int.
On Windows, 0 is returned if the command is successful.
On Windows we use spawnvp and on UNIX systems we use execv.
