linux中.bash_配置文件出现问题

我正在尝试设置类路径，但出现错误

文件代码：

当我回显Java类路径时，它打印为空

当我通过putty访问服务器时，出现以下错误：

-bash:$“\r”：未找到命令

---

-bash:/home/test/.bash\u配置文件：第16行：语法错误：意外的文件结尾

使用dos2unix.bash\u配置文件将Windows新行转换为UNIX新行。

使用dos2unix.bash\u配置文件将Windows新行转换为UNIX新行。

语法错误可能与CRLF和CR有关，您可以通过在linux端编辑该文件或使用丰富的编辑器（如记事本+）来解决此问题，您可以使用linux新行保存该编辑器，请参阅

此外，您可能希望在.bashrc中编写这些脚本

我的linux机器上的bash手册页上说：

FILES
   /bin/bash
          The bash executable
   /etc/profile
          The systemwide initialization file, executed for login shells
   ~/.bash_profile
          The personal initialization file, executed for login shells
   ~/.bashrc
          The individual per-interactive-shell startup file
   ~/.bash_logout
          The individual login shell cleanup file, executed when  a  login
          shell exits
   ~/.inputrc
          Individual readline initialization file
   /etc/inputrc
          System readline initialization file

根据这一点，OS X上的terminal.app是一个例外

Mac OS X — an exception
An exception to the terminal window guidelines is Mac OS X’s 
Terminal.app, which runs a login shell by default for each new
terminal window, calling .bash_profile instead of .bashrc. Other 
tGUI terminal emulators may do the same, but most tend not to.
