-bash: /etc/bashrc: line 127: syntax error near unexpected token `then' -bash: /etc/bashrc: line 127: ` if [[ $first_type ]];then'

当你看到这样的错误提示 `-bash: /etc/bashrc: line 127: syntax error near unexpected token 'then''
-bash: /etc/bashrc: line 127: ` if [[ $first_type ]];then'`，这意味着你在Bash shell脚本 `/etc/bashrc` 的第127行遇到了语法错误。在这个错误中，`then` 关键字意外地出现在了解析器预期的某个地方之前。通常这种错误发生在条件语句（如if...then...else...）的结构中，可能是括号、花括号或者引号没有正确配对，或者是命令选项书写格式有误。

解决这个问题需要检查那行的具体内容，看看是否漏掉了开始的大括号 `{}` 或者结束的大括号 `}` 来包围应该由 `if` 开始的代码块。例如，正确的格式应该是：

if [[ $first_type ]]; then
    # 你的命令或代码...
fi

建议使用文本编辑器打开文件，仔细检查127行及其上下文，并确保所有条件语句的结构都是完整的。如果不确定如何修复，可以尝试复制出有问题的片段并粘贴到在线的Bash语法验证工具中检查。

-bash: /home/EPRobot/.bashrc: line 6: syntax error near unexpected token `$'in\r''

这个错误可能是因为你的`.bashrc`文件中有一个格式错误。请检查你的`.bashrc`文件并尝试修复错误。这个错误通常表示在文件中有一个不正确的字符或语法错误。你可以使用以下命令打开你的`.bashrc`文件进行编辑：

nano ~/.bashrc

然后查找第6行附近是否有任何格式错误或语法错误，修复它们并保存文件。最后，使用以下命令使更改生效：

source ~/.bashrc

-bash: .bashrc: line 14: syntax error near unexpected token `newline' -bash: .bashrc: line 14: `<configuration>'

It seems like there is an error in the syntax of your .bashrc file on line 14. The error message suggests that there is an unexpected token, possibly a newline character, in that line.

To fix this error, you should open your .bashrc file and check the syntax of line 14. Make sure that all opening and closing brackets, quotes, and other special characters are properly placed and balanced. Also, make sure there are no extra or missing characters in that line. Once you have corrected the syntax error, save the file and refresh your terminal session.
