Linux：查看 .jar 文件内容的最便捷方法是什么

Question

使用 unzip/untar 命令查看 .jar 文件内容的最便捷方法是什么？我想要做的 - 是使用cd命令浏览内部，就像通常的文件夹一样，查看内容，类的大小 - 'ls -la'。

MC允许即时这样做。是否有任何易于使用的替代方案？

Answer 1

使用 Java SDK 附带的 jar 工具列出 jar 文件的内容。如http://docs.oracle.com/javase/7/docs/technotes/tools/windows/jar.html 中所述

$ jar tvf jarfile.jar

Answer 2

使用 vim 无需解压即可查看和编辑 jar 文件的内容：

像这样在vim中打开罐子：

vim rabbitmq-client.jar

您将看到一个文件列表：

1 " zip.vim version v22
2 " Browsing zipfile /var/www/sandbox/eric/rabbitmq-client.jar
3 " Select a file with cursor and press ENTER
4
5 META-INF/
6 META-INF/MANIFEST.MF
7 com/
8 com/rabbitmq/
9 com/rabbitmq/client/
10 com/rabbitmq/client/impl/
11 com/rabbitmq/client/impl/recovery/
12 com/rabbitmq/tools/
13 com/rabbitmq/tools/json/
14 com/rabbitmq/tools/jsonrpc/
15 com/rabbitmq/utility/

将光标放在 上META-INF/MANIFEST.MF并按Enter。你看到这个：

使用普通的 vim 编辑命令更改几行。

press 'i' to enter insert mode
edit your lines
press :wq<enter> to write and quit

您将返回到 jar 中的文件列表，退出。

:q <enter>

检查更改是否是永久性的：

Follow the above steps again to inspect the file again, 
the change should still be there.

Answer 3

这个对我来说总是足够的：

unzip -l <jarfile>

Answer 4

我认为.jar文件本质上就是.zip文件。所以，我想，fuse-zip可以工作。
