Replace line in file with line in another file based on matching string
HI

Can any one guide me how to achieve this task. I have 2 files

Code:
env.txt
#Configuration.Properties values
identity_server_url = http://identity.test-hit.com:9783/identity/service/user/register
randon_password_length = 6
attachment_file_path = /pass/temp/attachments/
documentation.services.basePath=http://appserver3.test-d.hit.com:9863/cirrus/service
documentation.services.version=2.0
user.registration.alert.path=emailtemplates/welcomeuser.vm

Code:
configuration.properties
identity_server_url = http://identity.test1-hit.com:9883/identity/service/user/register
randon_password_length = 8
attachment_file_path = /pass/temp/attachments/
documentation.services.basePath=http://appserver2.test1-d.hit.com:9863/cirrus/service
documentation.services.version=1.0
user.registration.alert.path=emailtemplates/welcomeuser.vm

In the above configuration.properties file i need to replace the line "identity_server_url" with env.txt file content. In configuration.properites file before '=' values are constant. After '=' values are changing. So i need to replace the line with matched string before '=' in configuration.properties with env.txt

Thanks
Nikil

avahi.service

avahi.service(5)						File Formats Manual						  avahi.service(5)

NAME

       avahi.service - avahi-daemon static service file

SYNOPSIS

       /etc/avahi/services/*.service

DESCRIPTION

       /etc/avahi/services/*.service are XML fragments containing static DNS-SD service data. Every service file can contain multiple service def-
       initions which share the same name. This is useful for publishing service data for services which implement  multiple  protocols.  (i.e.  a
       printer implementing _ipp._tcp and _printer._tcp)

XML TAGS

       <service-group> The document tag of avahi service files. Should contain one <name> and one or more <service> elements.

       <name replace-wildcards="yes|no"> The service name. If replace-wildcards is "yes", any occurence of the string "%h" will be replaced by the
       local host name. This can be used for service names like "Remote Terminal on %h". If replace-wildcards is not specified, defaults to "no".

       <service protocol="ipv4|ipv6|any"> Contains the service information for exactly one service type. Should contain one <type> and one  <port>
       element. Optionally it may contain one <domain-name>, one <host-name>, any number of <subtype> and any number of <txt-record> elements. The
       attribute protocol specifies the protocol to advertise the service on. If any is used (which is the default), the service  will	be  adver-
       tised on both IPv4 and IPv6.

       <type> Contains the DNS-SD service type for this service. e.g. "_http._tcp".

       <subtype> Contains an additional DNS-SD service subtype for this service. e.g. "_anon._sub._ftp._tcp".

       <domain-name>  The  domain  name this service should be registered. If omited defaults to the default domain of the avahi daemon. (probably
       .local)

       <host-name> The host name of the host that provides this service. This should be a host that is resolvable by  multicast  or  unicast  DNS.
       Please  note  that  you	need  to  specify a fully-qualified domain name (FQDN) here, i.e. .local is not appended implicitly! The host name
       doesn't need to be part of the domain specified in <domain-name>. See avahi.hosts(5) for more information how to  publish  additional  host
       name mappings.

       <port> The IP port number the service listens on.

       <txt-record> DNS-SD TXT record data.
