SYNOPSIS

11
12
13       options
14              The command-line options. See Options.
15
16       input-file
17              Name of the input file, which can be a pack200 gzip file or a
18              pack200 file. The input can also be JAR file produced by
19              pack200(1) with an effort of 0, in which case the contents of
20              the input file are copied to the output JAR file with the
21              Pack200 marker.
22
23       JAR-file
24              Name of the output JAR file.

DESCRIPTION

27       The unpack200 command is a native implementation that transforms a
28       packed file produced by pack200(1) into a JAR file. A typical usage
29       follows. In the following example, the myarchive.jar file is produced
30       from myarchive.pack.gz with the default unpack200 command settings.
31
32       unpack200 myarchive.pack.gz myarchive.jar

OPTIONS

36       -Hvalue --deflate-hint=value
37              Sets the deflation to be true, false, or keep on all entries
38              within a JAR file. The default mode is keep. If the value is
39              true or false, then the --deflate=hint option overrides the
40              default behavior and sets the deflation mode on all entries
41              within the output JAR file.
42
43       -r --remove-pack-file
44              Removes the input pack file.
45
46       -v --verbose
47              Displays minimal messages. Multiple specifications of this
48              option displays more verbose messages.
49
50       -q --quiet
51              Specifies quiet operation with no messages.
52
53       -lfilename --log-file=filename
54              Specifies a log file where output messages are logged.
55
56       -? -h --help
57              Prints help information about the unpack200 command.
58
59       -V --version
60              Prints version information about the unpack200 command.
61
62       -Joption
63              Passes option to the Java Virtual Machine, where option is one
64              of the options described on the reference page for the Java
65              application launcher. For example, -J-Xms48m sets the startup
66              memory to 48 MB. See java(1).

NOTES

69       This command should not be confused with the unpack command. They are
70       distinctly separate products.
71
72       The Java SE API Specification provided with the JDK is the superseding
73       authority in case of discrepancies.
74

EXIT STATUS

76       The following exit values are returned: 0 for successful completion,
77       and a value that is greater than 0 when an error occurred.
