Warning: The pack200 tool is deprecated, and is planned for removal in a future JDK release.
Usage: pack200 [-opt... | --option=value]... x.pack[.gz] y.jar
Packing Options
-r, --repack repack or normalize a jar, suitable for
signing with jarsigner
-g, --no-gzip output a plain pack file, suitable to be
compressed with a file compression utility
--gzip (default) post compress the pack output
with gzip
-G, --strip-debug remove debugging attributes (SourceFile,
LineNumberTable, LocalVariableTable
and LocalVariableTypeTable) while packing
-O, --no-keep-file-order do not transmit file ordering information
--keep-file-order (default) preserve input file ordering
-S{N}, --segment-limit={N} limit segment sizes (default unlimited)
-E{N}, --effort={N} packing effort (default N=5)
-H{h}, --deflate-hint={h} transmit deflate hint: true, false,
or keep (default)
-m{V}, --modification-time={V} transmit modtimes: latest or keep (default)
-P{F}, --pass-file={F} transmit the given input element(s) unchanged
-U{a}, --unknown-attribute={a} unknown attribute action: error, strip,
or pass (default)
-C{N}={L}, --class-attribute={N}={L} (user-defined attribute)
-F{N}={L}, --field-attribute={N}={L} (user-defined attribute)
-M{N}={L}, --method-attribute={N}={L} (user-defined attribute)
-D{N}={L}, --code-attribute={N}={L} (user-defined attribute)
-f{F}, --config-file={F} read file F for Pack200.Packer properties
-v, --verbose increase program verbosity
-q, --quiet set verbosity to lowest level
-l{F}, --log-file={F} output to the given log file,
or '-' for System.out
-?, -h, --help print this help message
-V, --version print program version
-J{X} pass option X to underlying Java VM
Notes:
The -P, -C, -F, -M, and -D options accumulate.
Example attribute definition: -C SourceFile=RUH .
Config. file properties are defined by the Pack200 API.
For meaning of -S, -E, -H-, -m, -U values, see Pack200 API.
Layout definitions (like RUH) are defined by JSR 200.
Repacking mode updates the JAR file with a pack/unpack cycle:
pack200 [-r|--repack] [-opt | --option=value]... [repackedy.jar] y.jar
Exit Status:
0 if successful, >0 if an error occurred

-g, --no-gzip | output a plain pack file, suitable to be compressed with a file compression utility | help + man |
--gzip | (default) post compress the pack output with gzip | help |
-G, --strip-debug | remove debugging attributes (SourceFile, LineNumberTable, LocalVariableTable and LocalVariableTypeTable) while packing | help + man |
-O, --no-keep-file-order | The packer reorders and transmits all elements. | help + man |
--keep-file-order | Preserve the order of files in the input file. | help + man |
--segment-limit, -Svalue N | The value is the estimated target size N (in bytes) of each archive segment. | help + man |
--effort, -Evalue N | If the value is set to a single decimal digit, then the packer uses the indicated amount of effort in compressing the archive. | help + man |
--deflate-hint, -Hvalue h | Overrides the default, which preserves the input information, but can cause the transmitted archive to be larger. | help + man |
--modification-time, -mvalue V | transmit modtimes: latest or keep (default) | help + man |
--pass-file, -Pfile F | Indicates that a file should be passed through bytewise with no compression. | help + man |
--unknown-attribute, -Uaction a | Overrides the default behavior, which means that the class file that contains the unknown attribute is passed through with the specified action. | help + man |
--class-attribute, -Cattribute-name N}={L | (user-defined attribute) | help + man |
--field-attribute, -Fattribute-name N}={L | (user-defined attribute) | help + man |

--config-file, -f F | A configuration file, containing Java properties to initialize the packer, can be specified on the command line. | help + man |
-v, --verbose | increase program verbosity | help + man |
-q, --quiet | Specifies quiet operation with no messages. | help + man |
--log-file, -lfilename F | output to the given log file, or '-' for System.out | help + man |
-?, -h, --help | Prints help information about this command. | help + man |
-V, --version | Prints version information about this command. | help + man |
