Need help in retrieving log from a UNIX file using the search patterns

Hi everyone,

I am trying to retrieve certain log from a big file. The log size can be from 200 - 600 lines. I have 3 search patterns, out of which 2 (first and last lines) search patterns are common for all the transactions but 3rd search pattern (occurs in the middle of transaction) is unique.

Now, using these three search patterns, I want to retreive the complete transaction log (start to end) into a seperate file.

I think, this can be done using awk. I know the basic awk commands but not comfortable with the awk programming.

Can anyone help me on this? Thanks in advance.
