Hi:

Try: gzcat backup.tar.gz | tar -xvf - specific_file
Note that file must match the name when it was stored. You may need -tvf to get the right name.

To extract the compressed tar archieve target.tar.gz OR .tgz into the current directory in a single step:

# gzip â d target.tar.gz | tar xf â
OR

To list .tgz archieve
# gzip -dc DIRECTORY.tgz | tar tvf -

Hi,
The following example would help.

#tar -tvf test.tar
rwxrwxrwx 0/3 0 Aug 3 10:26 2010 test/
rw-rw-rw- 0/3 0 Aug 3 10:26 2010 test/cac
rw-rw-rw- 0/3 0 Aug 3 09:50 2010 test/a1
rw-rw-rw- 0/3 0 Aug 3 09:50 2010 test/a2

To extract get cac file

#tar -xvf test.tar test/cac
x test/cac, 0 bytes, 0 tape blocks
