Search and update line??

[Guest_imported]

Hi,

I have a file x which contains few line.

<.... port=8080 security=on....>

I have to search for the above line where port number is 8080 and update the value of security=off in that line. I have to write this in a shell script.Could anyone please
suggest me how to do so.

Thanks

Why can't you just vi the file ?
You wouldn't be trying to hack into web servers would you ?
