untar to a specific directory

[Donald Thaler]

file was created as tar-cvf file.tar /u01/app/oracle/product/10.2.0


i want to untar it into /u04 what would the command be ??

[melvyn burnard]

I would take a look at using pax to read the tar archive and strip/change the leading directories, as this has been created with absolute paths.
man pax

you might be able to do something with chroot, then move the files afterwards.

In future don't create the tar files with the fill path.

As Melvyn said you need to use pax or GNU tar:
pax -f file.tar -r -s":/u01:/u04:"

[Donald Thaler]

what is the command I should have executed which would have allowed me to create a tar file from the directory /u01/app/oracle/product/10.2.0, and allow me to untar it to a /u04 directory. ?

What is a 'fill path' ?

Use "cd" to get past the part of the path
which you don't want, and don't use a leading
slash in the "tar" command. For example:

cd /u01
tar cf x.tar app/oracle/product/10.2.0

cd /u04
tar xf ../u01/x.tar

(Of course, if you just wanted to copy the
whole tree, a pipeline could obviate the
"tar" archive itself.)

What's the key jist to the left of the "I"?

Why worry about it when you have a better utility pax, that allows renaming?

Hi

To achieve that i would always do it that in a way like

#cd /u01/app/oracle/product/10.2.0
#tar cvf /u04/file.tar *

Once that is over , go to another directory say /u04

#cd /u04
#tar xvf file.tar .

you can also take the help of fbackup if like

#cd /u01/app/oracle/product/10.2.0
#fabckup -0vf /u04/file.back /u01/app/oracle/product/10.2.0

#cd /u04
#frecover -rXf file.back

I would (almost) never use "*" that way. It
will miss dot-names (like ".profile"), and
the result might exceed the command line
length limit (if "*" expands to a long list).

Why "."? Did you try this?
