Top Forums Shell Programming and Scripting How to avoid TAR of directory with no permissions? Post 302782139 by rajangupta2387 on Monday 18th of March 2013 10:50:39 AM

Hi Guys,

Thanks for reply. I am using solaris. And i am in process of design a shell script in bash which tar all the files mentioned as a regular expression and removes them from the location(just like recycle bin functionality) and when a particular file or directory is not able to tar completely it should ignore and tar rest of them. i have a seprate log which shows which files/dir have been tar or not tar.
Rest everything is working fine except that the when unable to tar the directory the tar file still kept the empty directory which on restoring replaces the original directory with contents which is incorrect.

If tar is not done it should not store this directory at all. How can i prevent the tar of such directories.

Hope this helps in better understanding of the issue here.

Thanks and Regards
Rajan Gupta

Another option that came in my mind is to remove the directory in tar. I know it is possible througfh exclude folder but in my case this is not working. Can anyone highlight the case how can i remove the exesting non permission empty directory from tha tar created so that i have a clean tar.

Regards
Rajan

This man page documents version 1.2 of libtar. DESCRIPTION
The th_get_*() functions extract individual fields from the current tar header associated with the TAR handle t. The TH_IS*() macros are used to evaluate what kind of file is pointed to by the current tar header associated with the TAR handle t. The TH_ISLONGNAME() and TH_ISLONGLINK() macros evaluate whether or not the GNU extensions are used by the current tar header associated with the TAR handle t. This is only relevant if the TAR_GNU option was used when tar_open() was called. SEE ALSO
