Top Forums Shell Programming and Scripting Backingup larger files with TAR command Post 302940874 by Corona688 on Thursday 9th of April 2015 02:27:42 PM

The data is compressed, you need to pass it through gunzip before tar can understand it again.

Code:
dd if=/path/to/rewindingtapedevice | gunzip | tar -tf -

That will just list files. Change -tf into -xf or -xvf once you're sure it's finding the files.

Again, there is probably a better way to use tapes on AIX specifically, but that's beyond my knowledge, this is a generic UNIX fashion.

#include <libtar.h> char *th_get_linkname(TAR *t); char *th_get_pathname(TAR *t); mode_t th_get_mode(TAR *t); uid_t th_get_uid(TAR *t); gid_t th_get_gid(TAR *t); int th_get_crc(TAR *t); off_t th_get_size(TAR *t); time_t th_get_mtime(TAR *t); major_t th_get_devmajor(TAR *t); minor_t th_get_devminor(TAR *t); int TH_ISREG(TAR *t); int TH_ISLNK(TAR *t); int TH_ISSYM(TAR *t); int TH_ISCHR(TAR *t); int TH_ISBLK(TAR *t); int TH_ISDIR(TAR *t); int TH_ISFIFO(TAR *t); int TH_ISLONGNAME(TAR *t); int TH_ISLONGLINK(TAR *t); VERSION
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
