AIX & TAR related stuff
This thread is about using tar & other compression utilities on AIX ;

1. Find out which version of tar you are using
thanks to bakunin

Code:
>what $(which tar)
/usr/bin/tar:
        61      1.14  src/bos/usr/ccs/lib/libc/__threads_init.c, libcthrd, bos53  0 7/11/00 12:04:14
        10  1.49.1.75  src/bos/usr/bin/tar/tar.c, cmdarch, bos53A, a2004_38A1 8/  31/04 07:07:20

2. GNU Tar

why it is important to know which version of tar you are using ?

Code:
# tar cvf - file | gzip > file.tar.gz
tar: 0511-825 The file 'file' is too large.

AIX tar has a 2 GB limit to the file size. On UNIX tar there are some limits: avg. 12 GB of file archive (may vary depend of UNIX flavor), 6 level of directories (all UNIX, but not GNU tar), 32k directories on one level (this is a limitation of JFS and JFS2) Use tar from the Linux Toolbox CD - can get it alternatively here: https://www14.software.ibm.com/webap...G=tar&cp=UTF-8
or
Welcome to Bull AIX freeware site
ftp://ftp.software.ibm.com/aix/freeS...aix5.1.ppc.rpm

Procedure
Find the native AIX tar location.
Code:
#which tar
/usr/bin/tar

Move the native binary tar command:
Code:
#cd /usr/bin
#mv tar tar_

Install the GNU tar, which can be obtained from the AIX toolbox site: IBM AIX Toolbox download information
Set the install location to be something similar to /opt/freeware/bin/tar

Create a gnu tar soft link:
Code:
ln -s  /opt/freeware/bin/tar /usr/bin/tar

Validate that the tar command is gnu tar:
Code:
#tar --version



3. Popular Tar options

-c = create
-f = read to/from the named file (instead of the device /tape)
-t = list contents of .tar file
-r = append to a .tar file
-v = verbose (tells you everything its doing)
-x = extract contents of .tar file
-z = compress files


4. tar: 0511-169 A directory checksum error on media ; 804399360 not equal to 12401.
