Shell Programming and Scripting

Dear Friends,
Here I am with another difficulty. I have a flat file from which I wanna grep following pattern.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Statement Date : Blah blah
Blah blah
Blah blah
Blah blah
Blah blah
...
...
...
..
..
....
...
..
Blah blah
Blah blah
Blah blah Blah blah Blah blah Invalid Statement
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Here I want the script to search for “Invalid Pattern” word. And if the script finds “Invalid Pattern” word then it should grep the portion from Statement date to “Invalid Pattern” word.

Please guide me to do this.
Thank you in advance.

I would suggest to separate "paragraphs" with a blank line such that the file will look like this:

Code:

Statement Date : Blah blah
Blah blah
Blah blah
Blah blah Blah blah Blah blah Invalid Statement
Blah blah Blah

Statement Date : Blah blah
Blah blah
Blah blah
Blah blah Blah blah Blah blah Invalid Statement
Blah blah Blah

Once the file is in the above format, you can use this:

Code:

sed -e '/./{H;$!d;}' -e 'x;/Invalid Statement/!d;'
