tar: blocksize = 0 - Error message?
Hi All,

While viewing tar file using "tar tf file.tar" command, I have received
"tar: blocksize = 0" message and while extracting a particular file from the same tar file (file.tar) I have received the same message and nothing is extracted.

Above commands ran in a shell script so, I manually re-viewed and extracted it then it is OK.

Please let me know what would be the problem?

Thanks.

I have only seen the "tar: blocksize = 0" message when the tar file being extracted is zero-length. Is it possible in the script you are specifying another file by mistake or, perhaps, the tar filename is correct but is actually zero-length at that time?

If it works manually, I suspect there is an error in the script. Try doing an "ls -l file.tar" immediately before the tar list in the script to verify its size.

Try running the script with the -x option. This is more often then not caused by a typo in the filename or in a variable.

Hi Hegemaro / Reborg,

As both of you said, it has been executed with -x option and file should be empty while testing by tar tf option.

Thanks a lot for your both help.
