I related your last two post, and i tried the following..
Hope this will remove your blocking... Smilie

$cat file

DEV_1_SOURCE_DATABASE=server1
DEV_1_SOURCE_AUDIT_DATABASE= server1
DEV_1_TARGET_DATABASE=server4
DEV_1_TARGET_AUDIT_DATABASE=server4

DEV_2_SOURCE_DATABASE=server2
DEV_2_SOURCE_AUDIT_DATABASE= server2
DEV_2_TARGET_DATABASE=server5
DEV_2_TARGET_AUDIT_DATABASE=server5

Solution 1:

script1.sh
a=` cat file | grep -w "DEV_2_TARGET_DATABASE" | cut -d '=' -f 2`
sed "s/\($a\)/newdb/g" file > file1
mv file1 file

The above script will take the value assigned for DEV_2_TARGET_DATABASE, and substitute that value i.e "server5" to newdb in the whole file content. ( even for DEV 4 or DEV 3)

Solution 2:

If you want to substitute only DEV_2_TARGET_DATABASE=server5 to DEV_2_TARGET_DATABASE=newdb

sed "s/\(DEV_2_TARGET_DATABASE=\)\(.*\)/\1newdb/g" file

Hope this helps..

GENTEST(1)							  [FIXME: manual]							GENTEST(1)

NAME

       gentest - Run random generic SMB operations against two SMB servers and show the differences in behavior

SYNOPSIS

       gentest {//server1/share1} {//server2/share2} {-U user%pass} {-U user%pass} [-s seed] [-o numops] [-a] [-A] [-i FILE] [-O] [-S FILE] [-L]
	       [-F] [-C] [-X]

DESCRIPTION

       gentest is a utility for detecting differences in behaviour between SMB servers. It will run a random set of generic operations against
       //server1/share1 and then the same random set against //server2/share2 and display the differences in the responses it gets.

       This utility is used by the Samba team to find differences in behaviour between Samba and Windows servers.

OPTIONS

       -U user%pass
	   Specify the user and password to use when logging on on the shares. This parameter is mandatory and has to be specified twice.

       -s seed
	   Seed the random number generator with the specified value.

       -o numops
	   Set the number of operations to perform.

       -a
	   Print the operations that are performed.

       -A
	   Backtrack to find minimal number of operations required to make the response to a certain call differ.

       -i FILE
	   Specify a file containing the names of fields that have to be ignored (such as time fields). See below for a description of the file
	   format.

       -O
	   Enable oplocks.

       -S FILE
	   Set preset seeds file. The default is gentest_seeds.dat.

       -L
	   Use preset seeds

       -F
	   Fast reconnect (just close files)

       -C
	   Continuous analysis mode

       -X
	   Analyse even when the test succeeded.
