How to extract the number from the pattern
Hi
I have a file with the following entries:
Code:
cm2363db
cm2445db
cm2618db

Is there a awk or sed command which would allow me to extract only the numbers from this file as output, so the output would look like this:
Code:
2363
2445
2618


Thanks a lot -A

or with gnu grep:

Code:
grep -oE '[0-9]+' file

That will put each set of numbers on a new line, not what the OP wants.
