ok, where did you find this ??? search a lot of different places and can't seem to find the link you're talking about.

:-(

The source code for head can be found by going to http://www.opensource.apple.com//projects/darwin/1.3/projects.html
and downloading the text_cmds package. (tar.gz file) Make sure you have the
developer stuff installed and use the make command in the head folder.

Delete /usr/bin/HEAD ( this is an exact duplicate of GET,POST, and lwp-request so nothing is lost)
copy head to /usr/bin as root or using sudo and make the ownership and permissions the same as tail.

[melton-henry-1:/usr/bin] rhca80% sudo chown root head
[melton-henry-1:/usr/bin] rhca80% sudo chmod 555 head
[melton-henry-1:/usr/bin] rhca80% sudo chgrp wheel head
[melton-henry-1:/usr/bin] rhca80% ls -al head tail
