Hello!

I am trying to move the directories and files from hp-ux 11.0 to hp-ux 11i. What command should i used? I can do rcp for moving files but not for directories via remote.

Please advise,
Adrianne

Adriane, I would recommend you to use fbackup/frecover to move data, also you can use tar to do the job, if you have really big files, there is a patch to support files bigger than 2 GB's.

jaime.

Shalom,

usually rcp -rp will move files and directories, tough what it is really doing is copying them, which is better anyway.

Make sure your system is patched becuase I've seen errors with rcp -rp

scp -rp is better. More reliable and secure

tar copy across and untar is best because it does the best job preserving permissions.

Don't forget to migrate your users if you use /etc/passwd file authentication.

I prefer tar or cpio across the network to rcp.

something like:

(cd /source; find . -xdev | cpio -o | ssh destination "cd /target && cpio -idumv")

Under root:

/>>rcp -rp /procedures hostname: /procedurces

Do I need to mkdir first or i can just move the everything over?

Thanks,
Adrianne

I prefer tar, because it does the best job of preserving permissions (as mentioned above).

It's pretty simple using tar and ssh across the two machines.

from source machine:

cd /sourcedir
tar cvf - . | ssh destmachine "cd /destdir; tar xvf - "

If you don't have ssh configured (and you should) you can remsh just as easily as above, just substitute the "ssh" part for "remsh" - works pretty much same way.

Tar and cpio have one inherent drawback and that is maximum filesize (8GiB for a patched version of tar and 2GiB for cpio); the better alternative is to construct your remsh (or ssh) pipeline using fbackup and frecover. This will preserve all file attributes as well as handle large files with ease.
