How do I get the system CPU usage and give it in percent using bash, for example?

Sample output:

57%

In case there is more than 1 core, it would be nice if your average percentage could be calculated.

You can try:

top -bn1 | grep "Cpu(s)" | \

           sed "s/.*, *\([0-9.]*\)%* id.*/\1/" | \

           awk '{print 100 - $1"%"}'
