Hi Ed
sed does not parse your expression for dynamic strings
if you has fixed string then it can be write with sed.
however you can use grep for your needs more sensiblely Smilie

Code:
echo "ab01cde234"|grep -o "[0-9]*$"
234

if you want to use sed , maybe you can try like this
Code:
echo "ab01cde234" | sed 's/.*[a-zA-Z]\([0-9][0-9]*\)[A-Za-z]*/\1/g'
234

or
Code:
echo "abca121a1b01cde23412zxxx1212aa" | sed 's/.*[a-zA-Z]\([0-9][0-9]*\)[A-Za-z]*/\1/g'
1212

--ahamed
this expression only make this examples not global!.
for example
Code:
echo "ab01cde234AA" | sed 's/.*[a-z]\([0-9]*\)$/\1/g'
ab01cde234AA
