SED : Replace whole line on multiple execution

Hi,

I am have one file with a line

Code:
group=project_live

I need to replace it with line

Code:
group=project_live_support

before I execute some application related script.

The potentianl problem is when I replace this with sed using command

Code:
sed 's/group=project_live/group=project_live_support/g' [file-name]

for the first time it works fine. But depending on my business requirement I have to run the app-script multiple times. But for second time, it replaces and produces

group=project_live_support_support

3rd time,

group=project_live_support_support_support

Very Funny!! This happens due to replacement of string again and again

I have tried to replace the full line, not able to have a break-through. Do you have any ideas how the entire line can be replaced? The only requirement is to have string will have to be replaced with "group=project_live_support" should not change with multiple run.

Thanks in advance.

Regards,
Bhaskar

Code:
sed 's/group=project_live$/group=project_live_support/g' [file-name]
