Question Tar and un-tar issue
In AIX 5.3,

I have these directories:
HTML Code:
/lms
/lms/w_standard
/lms/d_admin
/lms/b_common
/lms/b_prodbus
/lms/d_prod
/lms/d_prod/ccldir
/lms/d_prod/ccluserdir
/lms/d_prod/config
/lms/d_prod/data
/lms/d_prod/log
/lms/d_prod/ocd
/lms/d_prod/print
/lms/d_prod/temp
/lms/reg
/lms/w_standard/prod_wh
and I want to make a tarball for only these directories, and move the tarball to another AIX node (AIX 6.1) and un-tar so that I can keep the exact directories and contents on the AIX 6.1 node.

Can you please advise on
1) how to make a tarball for only these specific directories and their sub-directories
2) how to un-tar the tarball so that it doesn't create duplicate directories on the target AIX node?

Appreciate it!

I am a little confused by your showing /lms and then some subdirectories originated in /lms. So, you do not want ALL files in /lms directory? If this is the case then I'd do following:

Code:
 cd /lms
 tar cvf your_tarball_file_name \
 w_standard \
d_admin \
b_common \
b_prodbus \
d_prod \
d_prod/ccldir \
d_prod/ccluserdir \
d_prod/config \
d_prod/data \
d_prod/log \
d_prod/ocd \
d_prod/print \
d_prod/temp \
reg \
w_standard/prod_wh

This command will place all files from subdirectories specified into a tarball. Copy it to the target machine and extract from it as follows:
Code:
 cd /your/target/folder
 tar xvf your_tarball_file_name

migurus,

Some of /lms' sub-directories are mounted. That is why you are seeing the mounted /lms/* directories.
I DO want all of the directories, their sub-directories, and all contents. I want to make everything into a tarball, and un-tar onto the target node.

Here, what would be the /your/target/folder? The target AIX node has the same directory structure as the source. So, /your/target/folder would be /lms, or just / ?

Please advise.

Yes, cd /lms on your target system

You can use absolute PATH with Unix tar:
Code:
tar cvf lms.tar \
/lms/w_standard \
/lms/d_admin \
/lms/b_common \
/lms/b_prodbus \
/lms/d_prod \
/lms/d_prod/ccldir \
/lms/d_prod/ccluserdir \
/lms/d_prod/config \
/lms/d_prod/data \
/lms/d_prod/log \
/lms/d_prod/ocd \
/lms/d_prod/print \
/lms/d_prod/temp \
/lms/reg \
/lms/w_standard/prod_wh

and on the destination node
Code:
tar xvf lms.tar

If you have ssh you can do it in one stroke:
Code:
tar cvf - \
/lms/w_standard \
/lms/d_admin \
/lms/b_common \
/lms/b_prodbus \
/lms/d_prod \
/lms/d_prod/ccldir \
/lms/d_prod/ccluserdir \
/lms/d_prod/config \
/lms/d_prod/data \
/lms/d_prod/log \
/lms/d_prod/ocd \
/lms/d_prod/print \
/lms/d_prod/temp \
/lms/reg \
/lms/w_standard/prod_wh | ssh destination_node tar xf -

---------- Post updated at 02:14 PM ---------- Previous update was at 01:55 PM ----------

Another method
Code:
find /lms -xdev -print

If this shows the correct files, transfer them with cpio like this
Code:
find /lms -xdev -print | cpio -o | ssh destination_node cpio -idm

/lms/d_prod/print \
/lms/d_prod/temp \
/lms/reg \
/lms/w_standard/prod_wh | ssh destination_node tar xf -

I have ssh set up between the two nodes, so I prefer this method.
I don't see the parent directory /lms on the command line.
What do we do with /lms ? Please advise.

It will create the needed /lms but maybe not with the original permissions (because they are not present in the tar file).
The cpio method will transfer the correct permissions for /lms.
