fastjar - archive tool for Java archives


fastjar -ctxu [OPTIONS] [jar-file] [manifest-file] [-C dir] files...


"fastjar" is an implementation of Sun's jar utility that comes with the JDK, written
entirely in C, and runs in a fraction of the time while being feature compatible.

If any file is a directory then it is processed recursively. The manifest file name and
the archive file name needs to be specified in the same order the -m and -f flags are


Exactly one of the following actions must be specified:

-c Create new archive.

-t List table of contents for archive.

-x Extract named (or all) files from archive.

-u Update existing archive.

The following parameters are optional:

-@ Read the names of the files to add to the archive from stdin. This option is
supported only in combination with -c or -u. Non standard option added in the GCC

-C directory
Change to the directory and include the following file.

-E Prevent fastjar from reading the content of a directory when specifying one (and
instead relying on the provided list of files to populate the archive with regard to
the directory entry). Non standard option added in the GCC version.

-M Do not create a manifest file for the entries.

-i Generate an index of the packages in this jar and its Class-Path.

-J All options starting with -J are ignored.

-0 Store only; use no ZIP compression.

Display version information.

-f archive
Specify archive file name.

-m manifest
Include manifest information from specified manifest file.

-v Generate verbose output on standard output.

Parameters of the form @option{@}FILE are considered to be names of files, and are
expanded with the contents of the file.

All remaining options are considered to be names of files.
