Question

我列出了我的jar文件的内容，如下所示：

jar -tf myjar.jar

但我想有选择地列出，例如所有以'm'开头的文件。以下不起作用：

jar -tf myjar.jar m*

我可以列出文件夹中的所有文件：

jar -tf myjar.jar folder/

但不是以'm'开头的文件：

jar -tf myjar.jar folder/m*

我有办法过滤列出的文件吗？

Answer 1

使用grep或egrep或类似的命令行实用程序，例如，

jar -tf myjar.jar | grep "folder/m"

jar命令本身不支持此类操作。使用grep / egrep /等工具是一种规范的解决方案，无论如何都是必不可少的工具。

Answer 2

您可以使用find命令和jar命令。这不会为您提供文件名起始模式的确切结果，但您可以接近。

没有find命令
