How do I create links from file to file?

" How do I create links from file to file? For example, I want to have an index.html file point to my home.htm file. "

This is accomplished in UNIX by using the ln command. To create a link "fileA.html" to "fileB.html":

ln -s fileB.html fileA.html

In your example, type: ln -s home.htm index.html

To find out more about the ln command or any other UNIX commands see the manual page on it at BSD (search for "ln" in this example).
