insert a line in a file

RishiPahuja · #1 (**permalink**) 06-21-2005

Hello guys,

Need to know how to insert a line at top of the file, without using temp files.
Can we do it on the fly?

Regards,
Rishi

here documents require << not < I think.
Generally I think it easier to read

Code:

echo "
1i
New Line Goes Here
.
wq
" | ex -s myfile
