add a string in the middle of a file

[ciro25]

want to add a string in a very top of a file without using VI or SED or AWK
this is what ive done:

(echo '0a'; echo 'LINE OF TEXT'; echo '.'; echo 'wq') | ed -s myfile

to add astrng right in the middle i could have count the lines of the file and just chenge the address.


EG. if file has 6 lines of text:

(echo '3a'; etc...etc...etc...)

Is there a method to do it where i do not need to know how many lines has a file, the script would add it straight in the middle?

Why do you want to do it "without using VI, SED or AWK"? How about Perl? Is there a reason to tie your hands?
