Mac OSX：找不到bash命令

Question

我是新手 - 我有一个新的iMac，安装了El Capitan和system python。我已经安装了几个库，包括xcode工具。当我在终端中输入bash命令时，我得到以下内容：

-bash：$：找不到命令

关于echo $ PATH：

/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin

在bash -x -l：

之后

我是否需要以某种方式改变我的路径才能找到命令？感谢。

您似乎正在输入$。这不是一个bash命令。
