extract data from file
My file in ksh consists of message data of varying lengths (lines), separated with headers.
I would like to find a string from this file, and print out the whole message data including the headers.

my plan of attack is to search the strings, print the top header, and print the whole message data below it.

i can't figure out the perfect awk command. i am creating this
situation for my own tool in data extraction. any ideas is
greatly appreciated.

$infile:

REPT header aaa 111
data1 data2 string1 string2
REPT header bbb 222
string1 data1
string2 data2 data3 data4
REPT header ccc 333
data1 data2 data3 data4
REPT header aaa 111
data1 data2 data3 data4
data5 data6
REPT header ddd 444
string1 string2
data1
data2

Look for: string1 and string2

$outfile:

REPT header aaa 111
data1 data2 string1 string2

REPT header bbb 222
string1 data1
string2 data2 data3 data4

REPT header ddd 444
string1 string2
data1
data2

mu-view

MU-VIEW(1)                                                    General Commands Manual                                                   MU-VIEW(1)

NAME

       mu_view - display an e-mail message file

SYNOPSIS

       mu view [options] <file> [<files>]

DESCRIPTION

       view  is the mu sub-command for displaying an e-mail message file. It works on message files and does not require the message to be indexed
       in the database.

       The command shows some common headers (From:, To:, Cc:, Bcc:, Subject: and Date:), the list of attachments and the plain-text body  of  the
       message (if any).

OPTIONS

       --summary
              instead of displaying the full message, output a summary based upon the first lines of the message.

       --summary-len=<number>
              Number of lines to use for the summary. Default: 5.

              --terminate  terminate  messaages  with  a  f  (form-feed) characters when displaying them. This is useful when you want to further
              process them.
