How to extract a portion of a string from a full string using unix.

For example:

Say source string is = "req92374923.log"

I want only the numeric portion of the string say "92374923" how to do that in Unix.

I suppose it depends on what you are really trying to do. One way would be:

Code:

echo req92374923.log | cut -c4-11

You can also use sed, awk or possible basename.
