unpack200 - Transforms a packed file produced by pack200(1) into a
JAR file for web deployment.
unpack200 [ options ] input-file JAR-file
- options
- The command-line options. See Options.
- input-file
- Name of the input file, which can be a pack200 gzip file or a pack200
file. The input can also be JAR file produced by pack200(1) with an
effort of 0, in which case the contents of the input file are
copied to the output JAR file with the Pack200 marker.
- JAR-file
- Name of the output JAR file.
The unpack200 command is a native implementation that
transforms a packed file produced by pack200(1) into a JAR
file. A typical usage follows. In the following example, the
myarchive.jar file is produced from myarchive.pack.gz with the
default unpack200 command settings.
unpack200 myarchive.pack.gz myarchive.jar
- -Hvalue
--deflate-hint=value
-
Sets the deflation to be true, false, or keep on all
entries within a JAR file. The default mode is keep. If the value
is true or false, then the --deflate=hint option
overrides the default behavior and sets the deflation mode on all entries
within the output JAR file.
- -r --remove-pack-file
-
Removes the input pack file.
- -v --verbose
-
Displays minimal messages. Multiple specifications of this option displays
more verbose messages.
- -q --quiet
-
Specifies quiet operation with no messages.
- -lfilename
--log-file=filename
-
Specifies a log file where output messages are logged.
- -? -h --help
-
Prints help information about the unpack200 command.
- -V --version
-
Prints version information about the unpack200 command.
- -Joption
-
Passes option to the Java Virtual Machine, where option is one of the
options described on the reference page for the Java application launcher.
For example, -J-Xms48m sets the startup memory to 48 MB. See
java(1).
This command should not be confused with the unpack
command. They are distinctly separate products.
The Java SE API Specification provided with the JDK is the
superseding authority in case of discrepancies.
The following exit values are returned: 0 for successful
completion, and a value that is greater than 0 when an error occurred.
