обмен переносными архивами (portable archive interchange)
Последствия ошибок (Consequences of errors)
If pax cannot create a file or a link when reading an archive or
cannot find a file when writing an archive, or cannot preserve
the user ID, group ID, or file mode when the -p option is
specified, a diagnostic message shall be written to standard
error and a non-zero exit status shall be returned, but
processing shall continue. In the case where pax cannot create a
link to a file, pax shall not, by default, create a second copy
of the file.
If the extraction of a file from an archive is prematurely
terminated by a signal or error, pax may have only partially
extracted the file or (if the -n option was not specified) may
have extracted a file of the same name as that specified by the
user, but which is not the file the user wanted. Additionally,
the file modes of extracted directories may have additional bits
from the S_IRWXU mask set as well as incorrect modification and
access times.
