a process, and inline anything that process sends to stdout in the template.
Based on a patch submitted by Peter Molettiere.
BE CAREFUL! this tag, depending on use, may allow you
to set something up so that users of your web
application could run arbitrary code on your server.
This can only happen if you allow unchecked GET/POST
submissions to be used as the command string in the
exec tag.
Usage:
From java:
SimpleHash root = new SimpleHash();
root.put( "exec", new freemarker.template.utility.Execute() );
...
From your FreeMarker template:
The following is executed:
${exec( "/usr/bin/ls" )}
