chmod problem

[Jeremy Henricks]

Hi,

I'm not sure if this is a bug, or just a well known problem with a
solution.

When using the "chmod" command on a file or directory that was previously
copied using the "cp -rp" command, the mode will not change. Instead, I see
the message, "Operation not permitted." However, if I run the "chmod"
command on a file or directory that I newly create, the command is
successful.

What am I doing wrong?

If there is a better place to ask this question, please let me know.

Thanks,

Jeremy Henricks
