If you want everyone to be able to read and write to /tmp/file.txt just log in as the owner or as root and at the command prompt (the $ represents the command prompt) type

Code:

$cd /tmp
$chmod a+rw file.txt

All users (a) will now have read and write access (+rw) but only the file's owner and root will be able to change the permissions or owner of the file.

If you would like to learn more about file permissions and how to change them take a look at these two tutorials http://www.start-linux.com/articles/article_57.php http://www.start-linux.com/articles/article_135.php

I wish you fun with linux,
