With HP's tar you can do it, but you can try gnu tar, it has an option to extract to a different dir. You can download it from;

Well if the tar archive was created with relative path, then simply go into the directory you wish to be in, and extract.
Otherwise, take a look at hte pax command, as this can read both tar and cpio commands, and can extract to a different path from a tar archive that has been created with absolute path names.
man pax

Hi 2,

Thx for yr advise, but u know say the tar file is 10G, actually u need 20GB to untar the file ( double size ) which I don't wanna to happen....any idea?

relative path is always easier.

Just do into another dir
Then do
#tar xvf /dev/rmt/?m

that should do it .

If you want absolute path files to be restored from tar then

check this doc

Well yes, if you have a 10G tar file and want to extract it you need an additional 10G to untar it, then you can remove the 10G tar file.

If you dont have space for this then all I can think of is gzip the tar file (which will still need a few more Gb to write the tar.gz file in the first place - but < 10G) then you can gunzip and untar at the same time - so youre using less space than 20G.
