exec() executes commands in the shell running on the local machine (where 
PHP is running), assuming it is allowed (for security reasons, it usually is 
not).  “http://machine2/script.sh” is not a command in any known shell 
script language.

Even if a Web server would serve that resource, it would not execute it by 
default, IOW by default you would receive only the source code of the shell 
script, not its output.
