sed/awk script to replace only FIRST comment in the file

Shell Programming and Scripting

My first comment on every file contains the license message. I want to replace with a new license message. I used the below sed script, which replaces all comments. What is the modification or any other method with awk script for the below to edit only the first comment(license message)?

#sed -f sedscript filename

sedscript:

/\/\*/,/\*\//{
        /\*\//i\
/*\
My New\
Copyright \
message\
*/
        d
}

Try this - removes lines from 1 to first occurrence of /, then cat s newcomment (assuming it contains /*.../) and rest of file together:

sed '1,/\*\//d' oldfile|cat newcomment -

Might be a non- uuoc?
