jartools

jartools is a command-line utility for examining java archives (JARs and WARs). It is a complement to (not a replacement for) the standard jar utility.

It is designed to use streams in the standard unix style so it can be composed with other stream-processing tools (e.g., grep, xargs).

Installing `jartools`

jartools is distributed as a rubygem. Install it like so:

$ gem install jartools

Depending on how your ruby is installed, you may need root privileges to do this.

It's been tested on Ruby 1.8.7, JRuby 1.5.6, and Ruby 1.9.2.

Using `jartools`

To see what tools are included in the version you have installed, you can do this:

$ jartools help

To get details on a particular tool, use, e.g.:

$ jartools help packages

This online help tells you what arguments may be passed to each command.
