Shell Programming and Scripting

Hi,
I need to replace an input IP address to an existing IP addresses.

Source input line is as follows:
--------------------

RequestURI := "sip: 123.1.1.1";

input IP = 124.10.3.4

My output should be

Request URI := "sip: 124.10.3.4";

I have written the code as follows:
$line =~ s/sip:.*;/sip:$RequestURI/;

After running the code i got the output as
RequestURI := "sip:124.10.3.4

In the above output (" this two charater are missing.
can you please help me to get those last two charaters.

Just add them to your replacement string:

Code:

$line =~ s/sip:.*/sip:$RequestURI\";/;
