Unzip and Concatenate the tgz Files Unzip and Concatenate the tgz Files
On a Linux host, login as root, change (cd) to the directory with the V34441-01.zip (4.3G), V34442-01.zip (4.3G) and V34443-01.zip (1.5G) files, and unzip the files using the unzip command. The next examples show how to unzip all three files.

# unzip 'V*.zip'
Archive: V34443-01.zip
inflating: OVM_EM12R2_3of3.tgz

Archive: V34442-01.zip
inflating: OVM_EM12R2_2of3.tgz

Archive: V34441-01.zip
inflating: OVM_EM12R2_1of3.tgz

3 archives were successfully processed.

Next, concatenate the three tgz files by typing “cat OVM_EM12*.tgz | tar -xzvf -” as shown in the next example.

# cat OVM_EM12*.tgz | tar -xzvf -

./OVM_EM12R2/
./OVM_EM12R2/em.img
./OVM_EM12R2/vm.cfg
./OVM_EM12R2/System.img

Once the “cat OVM_EM12*.tgz | tar -xzvf -” command completes, a directory named OVM_EM12R2 is created with three files; vm.cfg (4.0K), System.img (6.3G) and em12.img (28G). The vm.cfg file (4.0K) is the configuration file for the Oracle VM Template for Oracle Enterprise Manager 12c virtual machine. The System.img (6.3G) file is a virtual disk that contains the Oracle Linux 5U7 x86_64 operating system for the Oracle VM Template for Oracle Enterprise Manager 12c. The em12.img (28G) file is also a virtual disk that contains the /u01 directory with the Oracle Enterprise Manager 12c installation for the Oracle VM Template for Oracle Enterprise Manager 12c.

Relic HunterПроблема не в формате упаковки, а в размере файла.
Да.
CentOS 5, собран на основе RHEL 5, который использует патченый unzip-5.52.
Relic HunterШтатный unzip/gunzip разпаковывает файлы до 2гб
unzip-5.52-3.el5.x86_64, который установлен CentOS 5.8, да.
unzip-5.52- 6 , до 4Gb ;)
* Tue Jan 22 2008 Ivana Varekova <varekova@redhat.com>; - 5.52-6
- add 4GB patch (#429674)
Вообще, надо использовать unzip-6.0, который используется в RHEL 6 и CentOS 6:
* Tue May 25 2010 Karel Klic <kklic@redhat.com>; - 6.0-1
- Rebase to upstream 6.0
Resolves: #594860
- Fixed a buffer overflow (rhbz#532380, unzip-6.0-attribs-overflow.patch)
- Generate debuginfos (rhbz#540220, unzip-6.0-nostrip.patch)
- New upstream version
- Compiled using `make generic_gcc` (includes asm)
- Removed unzip542-rpmoptflags.patch, because RPM_OPT_FLAGS
are provided using command line
- Removed unzip-5.51-link-segv.patch, because the link file
is not reopened in the current version
- Removed unzip-5.51-link-segv2.patch, the bug was already fixed
in open_outfile in 5.52
- Removed unzip-5.52-toctou.patch (CAN-2005-2475), the vulnerability
is fixed in the current version
- Removed unzip-5.52-near-4GB.patch, unzip-5.52-near-4GB2.patch,
unzip-5.52-4GB3.patch, and unzip-5.52-4GB_types.patch, because
the current version supports large files
- Removed unzip-5.52-long-filename.patch, the current version
fixes the vulnerability by checking the length of command line
arguments in unzip.c
- Removed unzip-5.52-makefile.patch, because we no longer create
the link manually
- Removed unzip-5.52-open.patch, the current version uses umask.
- Removed unzip-5.52-cve-2008-0888.patch, the current version
fixes this vulnerability
- Ported unzip-5.52-249057.patch to current version (unzip-6.0-close)
Помимо, уже установленного у вас p7zip, можете скомпилировать новый unizp-6.0 RPM и обновить свой старый unzip-5.52.

Relic HunterВот тебе и 64 бит
Проблема в данной версии unzip.

В первом посте забыл упомянуть что, "# unzip 'V*.zip'" работает на RHEL6, OEL6 и CentOS6.

Помниться давно, у меня была похожая проблема на HP-UX11i. Стандартный "TAR" не мог работать с файлами больше 2Gb, пришлось устанавливать GNU TAR.

Relic HunterJek_a,

Осталась одна загадка в посте. Почему команда


все-таки отработала? Ведь .tgz означает архив с компрессией и должен был неявно вызваться штатный gunzip , никак не 7za.
Всё правильно:

"A tar archive file contains uncompressed byte streams of the files which it contains. To achieve archive compression, a variety of compression programs are available, such as gzip, bzip2, xz, lzip, lzma, or compress , which compress the entire tar archive."

Но! gzip <> unzip or gzip != unzip :))

"The gzip file format is specified in P. Deutsch, GZIP file format specification version 4.3, <ftp://ftp.isi.edu/in-notes/rfc1952.txt>, Internet RFC 1952 (May 1996). The zip deflation format is specified in P. Deutsch, DEFLATE Compressed Data Format Specification version 1.3, <ftp://ftp.isi.edu/in-notes/rfc1951.txt>, Internet RFC 1951 (May 1996)."
