[eric_204]

I have a tar file that contains some file with different names , i tried to extract the file with the * ( eg. tar -xvf file.tar /home/edp/* ) , but can't restore the files, could suggest how can I extract all the files ? thx.

[eric_204]

I tried restore it by the command "tar -xvf file.tar /home/edp/file1.* " then only the files begins with file1 will be restored , so I have use the below command to restore all the files , could suggest what could I do to restore all the files at one time without submit all the commands ?

"tar -xvf file.tar /home/edp/file2.* "
"tar -xvf file.tar /home/edp/file3.* "
"tar -xvf file.tar /home/edp/file4.* "
"tar -xvf file.tar /home/edp/file5.* "
"tar -xvf file.tar /home/edp/file5.* "
"tar -xvf file.tar /home/edp/file7.* "

I doubt if you can extract only a file or set of files matching a pattern if the files are part of the tar ball. (May be Iam wrong)

But if you want to extract all the files of file.tar into /home/edp then use

cd /home/edp ; tar xvf /absolutepathof/file.tar

This should extract all the files of file.tar in to the current directoy.

Thanks,

Hi Eric,

You can use the steps below to restore all files in one shoot :

# cd /home/edp
# tar -xvf file.tar /home/edp/file*

OR this to restore all :

# cd /home/edp
# tar -xvf file.tar

To list the contains of file.tar :

# tar -tvf file.tar

Hope this information can help you.

And don't forget to move file.tar into /home/edp first before executing the command that I refer to you.

Otherwise you interact with blank file 8-).

thx , but how can I restore it to current path instead create the path /home/edp ? thx.

Hi,

if the files are stored with absolute path names in the tar file, the standard tar command will not be able to relocate them.

If you need to extract them to a different directory directly you have to look for a new tar programm. I think GNUtar (gtar) can do this.

Search for it on the porting center (e.g. http://hpux.asknet.de).

Hope this helps

To do that, you could try to use pax instead of tar. Pax can handle tar files, but has options like -s to substitute patterns in the filenames...

pax -r -s///

Or use the -C option to change the root-directory used by tar to another directory, for instance /tmp, and then move the files to the correct location.

[Trond Haugen]

Filename substitution should work but you will need to escape special characters.
If you want to restore EVERYTHING from the tar archive use:
tar -xvf file.tar
If you wish to restore everything starting with a certain pettern use:
tar -xvf file.tar /home/edp/file[2-7].\*
If you want to restore to a different path like Stefan mentioned you can also look into pax which is part of HP-UX.

Hi Eric,

You can use the steps below :
For example :
other directory is /destination
file.tar at /tmp
need to restore /home/edp/*

# cd /destination
# pax -pe -rvf /tmp/file.tar -s '/^\///' /home/edp

Hope this information can help you.

Hi,
you can use pax. First, copy yout tar archive to the directory in which you want to unpack it, e.g.:
# cp mytararchive.tar /mytardir

then place yourself in the directory:

# cd /mytardir

and extract the files from mytararchive.tar:
# pax -rv -s'/^\///' < ./mytararchive.tar

which will create the dir. structure of the files in mytararchive.tar and append this structure to the current dir. It is a bit of a hack and I have not tried it with a single file, only the whole tar archive. You should of course always cd to the directory where you create your tar archive and select by ./ in order to avoid this situation in future.
