awk script to get words which are not in a particula order
Hi all,

I need a big help. I've a requirment which should be done in awk scripting only..
My requirment is:

In below file, there are some lines started with 'master replica:'.
i want to get the exact word in that line which should be before '@', and i've to create a file with these names line by line. Either the input file may contain multiple replicas or it may has only original replica.. But any of these both cases, it must contain the original replica..
Ex o/p:
replica1
replica2
original
*******************Sample File Contents*******************
replica "<replica1>"
2006-10-10T06:02:36+10 by Clearcase Admin Acct - xxxxxxx; xxxxxxx [xxxxxxx] (xxxxxxx@main_server)
"Replica for stm VOB /vobs/<vob_name>"
replica type: unfiltered
master replica: <replica1>@/vobs/<vob_name>
owner: vobadmin
group: xxxxxxxxx
host: "<replica_server1>"
identities: preserved
permissions: preserved
feature level: unknown
connectivity: connected
replica "<replica2>"
2006-10-10T06:02:36+10 by Clearcase Admin Acct - xxxxxxx; xxxxxxx [xxxxxxx] (xxxxxxx@main_server)
"Replica for stm VOB /vobs/<vob_name>"
replica type: unfiltered
master replica: <replica2>@/vobs/<vob_name>
owner: vobadmin
group: xxxxxxxxx
host: "<replica_server2>"
identities: preserved
permissions: preserved
feature level: unknown
connectivity: connected
replica "original"
2005-11-02T22:51:59+11 by ************* (***-**-*-@/**/*/*/*/)
"<Original_replica>"
replica type: unfiltered
master replica: original@/vobs/<vob_name>
request for mastership: enabled
owner: laserdev
group: xxxxxxxxx
host: "<main_server_alias>"
identities: preserved
permissions: preserved
feature level: 4
connectivity: connected
***************************************************
So It means that, the script should create a file with all replica names like in above mentioned example and it has to return (as an o/p) the host parameter of original replica.
For example, there is a replica with "original" name (see below for example), so under that original replica, there is a line which start with "host:", I want to get that <main_server_alias> name as a o/p of the script.
*****************example one*************
replica "original"
2005-11-02T22:51:59+11 by ************* (***-**-*-@/**/*/*/*/)
"<Original_replica>"
replica type: unfiltered
master replica: original@/vobs/<vob_name>
request for mastership: enabled
owner: laserdev
group: xxxxxxxxx
host: "<main_server_alias>" ------> I want to get this <main_server_alias> name as a o/p of the script
identities: preserved
permissions: preserved
feature level: 4
connectivity: connected
*************************************

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
