Ot create a file and pipe something into it whatever you like you can use the redirect to a file

echo "hello" > /tmp/temp.txt

This will open a new file or overwrite an existing file in the same location and then put the text hello into /tmp/temp.txt. If you want to add addtional lines use the following command

Do you use the temporary file for anything in the meantime? I'm biased against temporary files when they can be avoided, personally... Why not stuff it all into a variable and then stuff it into a file when it's done, or just write directly to the destination file? Here's an example of using a variable:
