sed question
Hey Guys,
I am looking for a sed one liner to replace an entire line in a file with a certain pattern found. For example.

In logadm.conf.. replace the entire line containing '/var/adm/messages' with '/var/adm/messages -A 90d -C 0 -S 2g -p 1d -s 100m'

I have searched and found stuff about using the holding buffers but just cannot get it to work properly. Or is there an easier way to do this using awk? I have a 2 liner using grep however I want to simplify it.

Thanks

logadm.conf

logadm.conf(4)							   File Formats 						    logadm.conf(4)

NAME

       logadm.conf - configuration file for logadm command

SYNOPSIS

       /etc/logadm.conf

DESCRIPTION

       /etc/logadm.conf  is  the default configuration file for the log management tool logadm(1M). Comments are allowed using the pound character
       (#) and extend to the end of line. Each non-comment line has the form:

       logname options

       where logname is the name of the entry and options are the default command line options for the logadm command. The name of the	entry  may
       be  the	same  as  the  name of the log file, or a log file name may be given in the options section of the entry. Long lines may be folded
       using a backslash followed by a newline to continue an entry on the next line. Single or double quotes may be used  to  protect	spaces	or
       alternate-style quotes in strings.

       The  preferred  method  for  changing  /etc/logadm.conf	is to use the -V, -w, and -r options to the logadm(1M) command, which allow you to
       lookup an entry, write an entry, or remove an entry from /etc/logadm.conf.

       A full description of how and when /etc/logadm.conf is used and sample entries are found in logadm(1M).
