Sed Help Needed

Hello,

I have an ldif file in the following format:

dn: cn=AbruzRC,ou=ADVERTISING,ou=HQ,ou=NY,o=NYT
changetype: add
messageServer: cn=ADV-OA-01,ou=ADVERTISING,ou=BUSINESS,ou=HQ,o=NYTIMES

dn:cn=Advuser,ou=ADVERTISING,ou=HQ,ou=NY,o=NYTchangetype: add
messageServer: cn=ADV-OA-01,ou=ADVERTISING,ou=BUSINESS,ou=HQ,o=NYTIMES

I need to make every entry look as follows:

dn: cn=AbruzRC,ou=ADVERTISING,ou=HQ,ou=NY,o=NYT
changetype: modify
delete: messageServer
messageServer: cn=ADV-OA-01,ou=ADVERTISING,ou=BUSINESS,ou=HQ,o=NYTIMES

dn:cn=Advuser,ou=ADVERTISING,ou=HQ,ou=NY,o=NYTchangetype: modify
delete: messageServer
messageServer: cn=ADV-OA-01,ou=ADVERTISING,ou=BUSINESS,ou=HQ,o=NYTIMES

I have been trying the following:

sed 's/add/modify\nDelete:messageserver\n /' c:\ldifs\ms.ldif c:\ldifs\ms_del.ldif

Any help would be greatly appreciated. This is a windows machine however I felt I would get more help in the unix forum.

Thanks

Sorry file has entries that look like:

dn: cn=AbruzRC,ou=ADVERTISING,ou=HQ,ou=NY,o=NYT
changetype: add
messageServer: cn=ADV-OA-01,ou=ADVERTISING,ou=BUSINESS,ou=HQ,o=NYTIMES

Need to change to

dn: cn=AbruzRC,ou=ADVERTISING,ou=HQ,ou=NY,o=NYT
changetype: Modify
Delete: messageServer
messageServer: cn=ADV-OA-01,ou=ADVERTISING,ou=BUSINESS,ou=HQ,o=NYTIMES

this sure dont work

there are two probls: the sed statement and the parameters
sed (if not redirected) prints on stdout
sed sed-cmd inputfile >outputfile # does what you want
the statement (not really tested)
i did not spend time to do it on a cmd-line, put this in file
then use sed -f thatfile inputfile > outputfile
pay attention to the newlines, after 'a\' and '.*Server' they are NEEDED
-------------start here(not included)
/changetype: add/{ s/add/Modify/;a\
Delete: messageServer

}
----------- stop here(not included)
pay attention to spaces AND chars case
