 ==== Measure CPU load on all Droplets: ====
-./sshToServer.sh john all "top -bn1 | grep 'Cpu(s)' | sed 's/.*, *\([0-9.]*\)%* id.*/\1/' | awk '{print 100 - \$1}'"
+''./sshToServer.sh john all "top -bn1 | grep 'Cpu(s)' | sed 's/.*, *\([0-9.]*\)%* id.*/\1/' | awk '{print 100 - \$1}'"''
 it seems more accurate (or at least lines up better with DO usage stats) if a bit slower to catch the 2nd iteration of top instead of the first:
-./sshToServer.sh john all "top -bn2 | grep 'Cpu(s)' | sed 's/.*, *\([0-9.]*\)%* id.*/\1/' | awk '{print 100 - \$1}' | tail -n 1"
+''./sshToServer.sh john all "top -bn2 | grep 'Cpu(s)' | sed 's/.*, *\([0-9.]*\)%* id.*/\1/' | awk '{print 100 - \$1}' | tail -n 1"''
