Table 2-5: Type Flag Values for USTAR Format Files
In USTAR format, the uname and gname fields contain the name of the owner and group of the
file respectively. See also passwd(3).
Compressed tar archives are exactly equivalent to the corresponding archive being passed to
a 16-bit compress utility.
PORTABILITY
The
ASCII digit 7 is commonly used in the typeflag field to indicate contiguous files. The use
of 2 to indicate a symbolic link is particular to some
UNIX versions. These common exten-
sions are mentioned in the POSIX (IEEE P1003.1) standard.
