.Sh DIAGNOSTICS
|
|
The
|
|
.Nm
|
|
utility will exit with one of the following values:
|
|
.Bl -tag -width 2n
|
|
.It 0
|
|
All files were processed successfully.
|
|
.It 1
|
|
An error occurred.
|
|
.El
|
|
.Pp
|
|
Whenever
|
|
.Nm
|
|
cannot create a file or a link when extracting an archive or cannot
|
|
find a file while writing an archive, or cannot preserve the user
|
|
ID, group ID, file mode, or access and modification times when the
|
|
.Fl p
|
|
option is specified, a diagnostic message is written to standard
|
|
error and a non-zero exit value will be returned, but processing
|
|
will continue.
|
|
In the case where
|
|
.Nm
|
|
cannot create a link to a file,
|
|
.Nm
|
|
will not create a second copy of the file.
|
|
.Pp
|
|
If the extraction of a file from an archive is prematurely terminated
|
|
by a signal or error,
|
|
.Nm
|
|
may have only partially extracted the file the user wanted.
|
|
Additionally, the file modes of extracted files and directories may
|
|
have incorrect file bits, and the modification and access times may
|
|
be wrong.
|
|
.Pp
|
|
If the creation of an archive is prematurely terminated by a signal
|
|
or error,
|
|
.Nm
|
|
may have only partially created the archive which may violate the
|
|
specific archive format specification.
