Remove newline after `sudo` command, don't switch from `'` to `"` and use `filename` with full path or relative to root's home directory. – Cyrus Feb 25 '20 at 05:40

tried using single quotes also it doesnt work, and why should i remove new line after sudo command – Myjab Feb 25 '20 at 05:42

It should be `sudo sed -i "1 a sometext" filename` (and this is arguably what you should use interactively as well). The duplicate explains why it doesn't and can't work the way you tried it – that other guy Feb 25 '20 at 06:22
