Replace file with downloaded file linux

Can you please elaborate further? I want to understand why renaming a file isn't the same as replacing. For example, if I want to "replace" file1 with file2, why can't I just do: mv file2 file1? Does this command replace if file1 is removed first?

Replacing a text string in a file with Sed is done with the sed -i command.

First, open up a terminal window on the Linux desktop. Once the terminal window is open and ready to use, write out sed -i in the terminal prompt. This is the start of the replacement command. This quotation mark is essential, as all text being replaced with sed -i needs to start after this mark. When the text we want to replace is written into the command, the next step is to write in the new text that will replace it. It should look like the example below.

Finally, tell sed what file the text is in that needs replacing. The file is written to standard output and then redirected by the shell to the specified file as shown in the screen shot above.
