Topic: Tar (file format)


  
 Tar (file format) - Wikipedia, the free encyclopedia
This is probably a workaround for buggy tar implementations (the byte 0x00 is ASCII NUL).
Each file is preceded by a header block.
In computing, the tar file format is a type of archive file format: the Tape ARchive format.

The tar format for extended files is identical to the standard tar file format, except for the size field in the header block and the method for calculating the header block checksum.
A file on the tape is represented by a header block which describes the file, followed by zero or more blocks which give the contents of the file.
The tar format for extended files uses the same header block, but it encodes the file size as a hexadecimal number in ASCII format using all 12 characters.

 TAR archive file format
A file that is 513 bytes large thus occupies 512 bytes for the header, 513 bytes for the file's data, and 511 additional bytes so that the file content will be a multiple of 512 bytes (in this case, 1024 bytes).
If an archived file has a size in bytes which is not divideable by 512 without rest, as many bytes as missing to the next 512 byte boundary are added to fill up that last block.
Thus, reading the first 512 bytes of a potential tar file, creating that checksum and comparing it to the stored checksum will tell if the file really is in tar format.

 Cineon Tape File Format
Tar header blocks are used to create a header for each file on the tape.
The tape file format for Exabyte tape, Metrum tape, Ampex DST tape and the Ciprico parallel disks with tape emulation is based on the tar (tape archive) file format in common use in UNIX systems.
Each file entry is 184 bytes in length (including the tab characters between each field and the carriage return at the end of the entry).

The pax interchange file format is new with IEEE Std 1003.1-2001 (``POSIX.1'').
When extracting, GNU tar checks that the header file name is the one it is expecting, that the header offset is in the correct sequence, and that the sum of offset and size is equal to realsize.
This format is often called the ``ustar'' format, after the magic value used in the header.

Some file formats were not released by their creators, others are regarded as proprietary, which means that if your programs deal with them, you might be looking for trouble.
Each file archived is represented by a header record which describes the file, followed by zero or more records which give the contents of the file.
Such files are identified in Unix by each file having the same device and inode number.

 tar -- USTAR-compatible tape archiver to copy and back up files
Consider an analogy, where files are saved from a read-only file system (for example, a write-protected floppy disk), and restored to a read-write file system, such as the main hard drive.
When a file with a sparse attribute is extracted on a NTFS file system (which supports sparse files), the file is extracted as a sparse file.
The file permission modes of UNIX systems are not the same as those of Windows systems.

Incidentally, if the input file has fixed-length records, its size is computed using the record size and the size in blocks of the file.
VMS TAR automatically performs conversion of files to and from the UNIX file format, and converts between UNIX and VMS file protections and modification times.
When this is done, TAR knows the size of the file in bytes, so it can then write a header record to the real archive, and quickly load the contents of the temporary file into the archive.

 Keys to the kingdom - Penn Printout, Feb 95
Tar files typically end in a.tar extension, are binary files, and usually include nested directory and subdirectory information.
Because of this, it is common for tar files to subsequently be processed by one of the UNIX compression programs, resulting in gziped.tar.gz files or.tar.Z files.
Fortunately, it is usually possible to identify a file format by the filename extension, and that, combined with a knowledge of which program can decipher the file format, will allow you to manually convert the file into something usable.

 tar -- format of tar archives
Because the NTFS file system has fewer features than that of UNIX systems, much of the information stored in the archive is ignored.
The chksum field is a checksum of all the bytes in the header, assuming that the chksum field itself is all blanks.
Table 1 shows the format of the header block for a file, in the older UNIX-compatible TAR format.

 duplicity: New file format
Headers in index vs data: The file headers in the inner index file are the same as the file headers dispersed through the inner data file.
The inner data file is laid out similarly to tar, with a file header followed by its data.
Block headers: As in the outer file, block headers contain the length of the block along with a recognizable byte sequence.

 LEARN THE NET: File Formats & Extensions
All of the file formats found on the Internet can be broken into one of two types: ASCII format and binary format.
Occasionally you may encounter files with multiple extensions like.tar.gz, which usually means more than one type of software was used to compile and compress the file.
You need to identify the file type to know whether it will work on your computer and whether you will need a particular type of software to decompress, play, or view it.

Additional information about the project, including links to the project development page and file downloads, is available from the GNU software directory.
For example, you can use tar on previously created archives to extract files, to store additional files, or to update or list files which were already stored.
Despite the utility's name, tar can direct its output to available devices, files, or other programs (using pipes).

 The Source of All Tape Knowledge
The tar program is designed to write data out in blocks; it usually writes data out in an integer multiple of 512 bytes, as defined by the "b" option.
If you tar file does not include leading directories (for example, if you specified a file list instead of a directory hierarchy to tar up), it creates them with the wrong permissions (0440), and then cannot write the files or subdirectories into them.
Note that the null-byte padding in fixed block mode means that a file written to tape may have extra null bytes when you read it back in.
