sed string manipulation

hi
I am using sed to split a string
this string is 11byteabc I would like to just get the numeric digits.

Code:
echo "11byteabc" | sed 's/*[a-z]//

returns 11byteabc

only solution that works is repeating [a-z] number of times for the letters which is pointless

grateful for any suggestions
thanks

The correct syntax for the regex is :
Code:
echo "11byteabc" | sed 's/[a-z]//g'

or
Code:
echo "11byteabc" | sed 's/[^[:digit:]]//g'

Jean-Pierre.
