sed Command to skip

Friends,

I have 1000 line like below

 
#formate Test.server.e01=http://111.22.33.23/
#test_server_west
Test.server.w01=http://112.123.123.22/
Test.server.w02=http://113.143.123.22/
Test.server.w03=http://112.183.123.22/
 
#test_server_east
Test.server.e01=http://115.123.123.22/
Test.server.e02=http://112.143.123.22/
Test.server.e03=http://116.183.123.22/

my out put of the sed command should be like below

 
#formate Test.server.e01=http://111.22.33.23/
#test_server_west
Test1.server.w01=http://112.123.123.22/
Test1.server.w02=http://113.143.123.22/
Test1.server.w03=http://112.183.123.22/
 
#test_server_east
Test1.server.e01=http://115.123.123.22/
Test1.server.e02=http://112.143.123.22/
Test1.server.e03=http://116.183.123.22/

I need to replace all the string (Test/Test1) but , i need to skip the line which is starting with (#).

Could you please help me on this.

Thanks in Advance,
JB

May be:

sed '/^#/!s/Test/&1/g' file

With awk

awk '!/^#/ {sub(/Test/,"Test1")}1' infile

Jotne and elixir_sinari both seem to have missed that jothi basu asked not only for a "1" to be added but also for "T" to be changed to "t". And since "Test" always appears at the start of lines to be changed and only appears once, a simpler fix for the given data is:

sed 's/^Test/test1/' file

Of course, if the sample data is not representative, and "Test" actually does appear more than once in some lines or does not always appear at the start of a line, then the more complex scripts shown by others (with code to exclude comment lines) will be needed (with added changes to convert "T" to "t").

OP is not clear on the T/t. Example output

Test1.server.w01=http://112.123.123.22/

and

Test/test1

it is typo mistake , it is like (Test/Test1) only

And does it only appear at the start of the a line? Or, can it appear anywhere on a line? Can it appear more than once on a line?
