Hi, I was wondering if there could be an efficient way to get a
specified number of previous line texts from a very
large file while searching for a string text?

For example, I would like to get all the text within the
block marked between double dashes when the
searchfinds the string 'D : Error Occurred'.
Actually I only need the value of 'A' and 'B' only.

...
=================================
A : 123
B : 234
C : ABC
D : Error Occurred
=================================
