Question

extract a tar to a different path

Asked by: barthalamu

I would like to extract a tar archive that was made using full paths to a different sub-directory and NOT the full path that is contained in the tar.  Is there a way to "redirect" this from my existing tar archive?  Here is what I mean:

tar archive containing:
/usr/local/stuff/*

Extract to:
/mount1/...

I just want everything to be placed under a different directory, say mount1 in this example.  Thanks.

I don't know of a way to repath data from a tar archive as it is being extracted. However you can do:

mkdir /temp-place
cd /temp-place
tar xvf ....
mv usr/local/* /mount1

Use GNU tar (gtar) to extract the tarball. By default it will strip absolute paths (leading /). So, you can
go to some directory, gtar -x... to extract to there(.) and then move things wherever you want them.

GNU tar is delivered in the SUNWgtar package and normally it goes to  /usr/sfw/bin/gtar

I think Sun's tar stripps the leading / off of absolute paths also.

You need to first to go to mount1 directory and then give command

tar xvf  /usr/local/stuff/*

thats it!!!!!!!1

Sun has included the pax command with Solaris from 2.5 onward. This command can handle inline path replacement for archives (tar and cpio) using absolute paths. To convert an archive from absolute paths to relative paths, you just need to strip off the leading / . You can do this with the command below. Once the leading / has been removed, the file(s) will be extracted in the current directory (./usr/local/stuff instead of /usr/local/stuff ) and you should have no problem moving the files around.

pax -r -s ',^/,,' -f filename.tar

-r      read
-s      substitute       ',^/,,' will replace the leading forward slash with nothing
-f      filename
