====== SED - Change - Change string on a range of lines ======

<code bash>
sed '1,3 s/unix/linux/' filename
</code>

or

<code bash>
sed '2,$ s/unix/linux/' filename
</code>

<WRAP info>
**NOTE:**  **$** indicates the last line in the file.

So the sed command replaces the text from second line to last line in the file.
