I'd suggest the script creates a file (lock file or,
much easier, just a simple normal file) at its beginning:

	#!/bin/sh
	/usr/bin/touch /tmp/scriptrun
	# ... your script content here ...

You could also output the date command to that file
to see when the script has been called:

	#!/bin/sh
	/bin/date "+%Y-%m-%d %H:%M:%S" > /tmp/scriptrun
	# ... your script content here ...

Of course you would have to manually remove that file
after you have verified its existence and content.
