损坏的 usr/bin/java

损坏的 usr/bin/java

我刚刚做了一件非常愚蠢的事情，当我尝试通过输入以下命令将 JSTestDriver.jar 复制到 usr/bin/java 中时：cp jsTestDriver.jar usr/bin/java。

现在终端中的每个“java”命令都会打印出以下内容：

/usr/bin/java: line 1: PK: command not found
/usr/bin/java: line 2:Q?EA: command not found

我已经在 Google 上搜索过我的问题，但找不到解决方案。

我正在运行 Mac OS 10.6.8，它不支持 Java SE 7.0。我原本希望它能解决我的问题。

有人知道我如何恢复 /usr/bin/java 吗？

答案1

/usr/bin/java通常只是一个符号链接，有时指向你实际的 java 安装，有时指向类似的东西/etc/alternatives/java。

你使用什么 Java？Sun/Oracle？OpenJDK？你的发行版是什么？

运行命令：

find / -type f -name java

应该帮助您开始寻找真正的 Java 二进制文件。

答案2

只是为了确定：您能执行以下操作并发布结果吗？

readlink -f /usr/bin/java
file /System/Library/Frameworks/JavaVM.framework/Versions/A/Commands/java
/System/Library/Frameworks/JavaVM.framework/Versions/A/Commands/java -version
