I don't think you can use a wildcard when extracting as the shell would have nothing to match against before passing it to the tar command. You may need to have a two-step process:-
  • one pass with tar -t to get all files and use grep to filter out the filenames you want
  • seconds pass to extract the files you have determined are present in each tarfile.
It seems a little wasteful, but it should work. When it's working for a single tarfile, just put it in a loop for all the tarfiles.


I may be wrong though. What happens if you wrap the filename with the * in single quotes like this?
Code:
for file in *.tgz; do tar --wildcards -zxf $file '*results.txt'; done

This would pass the literal text including the * through to the tar command and might work.


I hope that this helps,
Robin

virt-tar-out(1) 					      Virtualization Support						   virt-tar-out(1)

NAME
virt-tar-out - Pack a virtual machine disk image directory into a tarball. SYNOPSIS
virt-tar-out -a disk.img /dir files.tar virt-tar-out -d domain /dir files.tar virt-tar-out -d domain /dir - | gzip --best > files.tar.gz DESCRIPTION
"virt-tar-out" packs a virtual machine disk image directory into a tarball. The first parameter is the absolute path of the virtual machine directory. The second parameter is the tar file to write. Use "-" to write to standard output. EXAMPLES
Download the home directories from a guest: virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-out" command. For anything more complex than a trivial copy, you are probably better off using guestfish directly. OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options. SEE ALSO
