sed prepend text ?
Hi,

I have a file with email header information. I would like to change the Subject line.

Code:
Subject: ** PROBLEM Host Alert: server.domainname is DOWN **

I'd like to change this line such as to look,
Code:
Subject: serverID ACK Fw: ** PROBLEM Host Alert: server1.domainname is DOWN**

How can I edit this? sed or anything else is fine.

Note: server1.domainname, is not always constant it could be server2, server3.domainname up until server30.domainname

ypinit

YPINIT(8)						    BSD System Manager's Manual 						 YPINIT(8)

NAME

     ypinit -- initialize NIS subsystem

SYNOPSIS

     ypinit -c [domainname] [-l server1,...,serverN]
     ypinit -m [domainname] [-l server1,...,serverN]
     ypinit -s master_server [domainname] [-l server1,...,serverN]

DESCRIPTION

     ypinit initializes the files and directories that are required for a NIS client or server.

     If domainname isn't specified, the default domain (as returned by domainname(1)) is used.

     The following options are available:

     -c      Create a NIS client.  Initializes /var/yp/binding/<domain>.ypservers to contain a list of ypservers for ypbind(8) to connect to.

     -l server1,...,serverN
	     Set the list of client servers from the command line rather than prompting for them interactively.  The format is a comma separated
	     list of server names with no spaces.

     -m      Create a master NIS server.  Generates map data from local files (/etc/master.passwd, /etc/group, etc.).

     -s master_server
	     Create a slave server.  Downloads the maps from master_server, which should be the active master NIS server.

     To rebuild or refresh the maps for the NIS domain <domain>, change to the /var/yp/<domain> directory and run make.

FILES

     /var/yp		 master NIS directory; contains the template makefiles.
     /var/yp/<domain>	 directory to store NIS maps for <domain>.
     /var/yp/binding/<domain>.ypservers
			 list of NIS servers to bind to.

SEE ALSO
