Extracting numbers from a string

Shell Programming and Scripting

Hello Everyone,

i have quick question.

I have file names like: bin_map300.asc and I would like to extract grid300.

My approach so far:

name=bin_map300.asc
echo ${name%%.*} 
echo ${name##*_}

I am stuck combining the two.

Any help would be appreciated.

[house@discovery] NAME='bin_map300.asc'; \
   echo "$NAME" | awk -F "[._]" '{print $2}'
map300

merci!
