OS utilities - SAPCAR

From today, I'l be posting short stream of more or less short blogs about OS utilities useful in life of SAP administrator.
It's little know-how from one of my colleagues and little add-on from me and internet. But it can be useful.

First in line is SAPCAR.

SAPCAR utility is application for packing/compressing and unpacking of files. It's mainly used for SAP installation packages, but if you want, you can use it on other files to. SAPCAR has 90-95% compress ratio for text files and lover compress ratio for binary files (I did not find later one).
On unix/AIX/linux you will find this utility in directory:
 usr\sap\<SID>\SYS\exe\run
and you should call it with upper-case.On windows, search for sapcar.exe


usage:
SAPCAR -xvf "<filter_for_files_to_extract>" - to extract files
SAPCAR -cvf <name_of_archuve> <files_to pack> - to pack and compress files
SAPCAR -xvf <file> -R <path>  - to give path where to unpack files (relative or absolute)

used parameters explanation:

-x	- extract data
-c	- compress data
-v	- verbose
-f <FILE>	- use archive file FILE (default DEFAULT.SAR)
-R <dir>	- use dir instead of current directory/td>

Note:
because Java packages are compressed in .zip format, do not use SAPCAR on them. Just unzip them (7zip or Winzip).
