perldoc -f exec
exec LIST
exec PROGRAM LIST
The "exec" function executes a system command *and never
returns*-- use "system" instead of "exec" if you want it to
return (Sic!).
perldoc -f system
system LIST
system PROGRAM LIST
Does exactly the same thing as "exec LIST", except that a fork
is done first, and the parent process waits for the child
process to complete (Sic!).
