How to automate emcgrab on multiple esx hosts?

I've got a management workstation and RSA keypairs set up so that authentication isn't an issue but I can't seem to automate the running of emcgrab across a few dozen hosts. I'd rather set it to run and walk away then to have to run it on every host individually. The script I'm running is below along with some output.

for i in `cat /tmp/testlist.txt` ; do scp -r /tmp/emcgrab/ $i:/tmp/ ; ssh $i chmod 777 -R /tmp/emcgrab/* ; ssh $i sh +x '/tmp/emcgrab/emcgrab.sh -legal -autoexec' ; done

THANK YOU FOR USING EMCGrab.

Any idea about what I'm doing wrong?
