Hi.

I have lots of files on one server and need to transfer them to another while preserving all permissions.
I tried tarring them up with :- tar -cfvp file.tar my_folder and it worked a little.. some of the files had permissions of 777 but TAR did not preserve them.. How do I get around this?

This is what my man page (AIX 4.2) says about tar's -p flag:

-p      Says to restore fields to their original modes, ignoring the present
umask. The setuid, setgid, and tacky bit permissions are also restored
to the user with root user authority.

Is this what you're looking for?

kind regards,

Yes, I understand this but I did have the "p" in the above example I have included
and it still didn't work.

I guess I included too much from the man page; just the last line was important here:
were you logged in as root while transfering the data? If not, check (and unset)
your umask ...

Hi.

Yes I was logged on as root. How do I unset my unmask? Sorry im not very experienced with this. Do I need to unset my unmask when tarring or when untarring?

Thanks for your help. Looks like we are getting somewhere, hopefully I will be right soon.

umask is a command (usage: 'umask 000' to unset all mask bits), but I think I've
got it now after rereading your question: you have to use the -p flag when
 _extracting_ the files, not when _creating_ the archive

(I guess I need glasses or something ;-)
