Re: have problem with tar -xvf

Hi Sani, I use tar like cp command, I have 02 HP-UX 11i v1 server and I want copy 1 directory from Server01 to Server02. I use tar to hold the user, group, permision of this directory not change.

Server01: #tar cvf - ./mydir | gzip > mydir.tar.gz
#rcp mydir.tar.gz Server02:/xxx

Server02: #gunzip mydir.tar.gzip
#tar -xvf mydir.tar

Hi,

The patch which you are having is quit old released on 2003. The latest tar cumulative patch is PHCO_36587.

Install this one along with dependencies and see the performance. Hopefully that may solve the issue.
Best wishes,

Ganesh.

Hi Tung ,

as u told it is not the same in every situation , you need to check the utilization of the server at that time.

Not the method I'd use. How many large
temporary files do you want? (You don't
_need_ any.)

( cd /src/path ; tar cf - stuff | gzip ) | \
remsh server2 ' ( cd /dst/path ; gunzip | tar xf - ) '

Variations:

If "/dst/path" doesn't exist, add
"mkdir -p /dst/path ; " before the "cd".

Substitute "ssh" for "remsh"

Add a "v" to one of the "tar" commands".
(With "v" on both "tar" commands, the noise
can be more confusing than helpful.)

Probably no one. Not enough info.

This is ok but if you have a problem when "cd somewhere" you will untar you files in the wrong directory or send files from a wrong directory or both (dangerous).


so better use && to test the return code

( cd /src/path && tar cf - stuff | gzip ) | \
remsh server2 ' ( cd /dst/path && gunzip | tar xf - ) '
