Adding lines of text to beginning of a text file


Hi folks,

I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.

I've wrestled with sed, but lost ... Any ideas would be much appreciated, cheers.

There are a lot of ways to do that. A sed command is 'i' which stats for insert a new line before the pattern. Specify only the first line as address and the trick is done:
Code:
sed -i.bak '1i text to add' file
