[awk]compare a number in a string with a list
Hi,

I have a program written in awk and I want to extend it to do another task.

My program is a list of CVS log reports of a repository. For each file, I have some fields. One of the fields is the comment field. I want to know how I can check if a comment (which is a free text field) contains a number and if it does, I want to check if that number exists in another list of numbers (taken as input from another file).

For example,
If the list of numbers is
Code:
100
101
102
103

And I have the following log data

Code:

This is some sample text. Bug 102: some text
=============================================================================

After the word "description", there can be 0, 1 or more commit data. In each commit data, I want to get the number from it, which can be anywhere in the 3rd or 4th line after the field separator "----------". And I want to compare that number with the list above and if it turns to be true, take some actions.

Can anyone help me how to do this. If needed, I can also send the already existing awk code I have.

Thanks,
Sandeep
