No Dude
Your scruipt will create new file "outfile" . but i should not create another file.. with in the existing file i need to append in first line
Example :

if my Header values is,
Code:
header="name,phone,number"

i want to append this header value in a file "sample.txt" has first line.

so after appending my sample.txt first line would be name,phone,number


Thanks,
Baski

You did not write you don't want a temp file Smilie

Code:
header="name,phone,number"
printf '1i\n'$header'\n.\nw!\nq!'| ex sample.txt

jayan_jay is by far the simplest, it does what is expected... Nothing is stopping you to:
Code:
mv outfile sample.txt
