tar
formatGNU tar
was based on an early draft of the
POSIX 1003.1 ustar
standard. GNU extensions to
tar
, such as the support for file names longer than 100
characters, use portions of the tar
header record which were
specified in that POSIX draft as unused. Subsequent changes in
POSIX have allocated the same parts of the header record for
other purposes. As a result, GNU tar
format is
incompatible with the current POSIX specification, and with
tar
programs that follow it.
In the majority of cases, tar
will be configured to create
this format by default. This will change in future releases, since
we plan to make ‘POSIX’ format the default.
To force creation a GNU tar
archive, use option
‘--format=gnu’.
