Mac OSX：没有找到bash命令

Question

我是一个新手 - 我有一个新的与El Capitan和系统python安装的iMac。我已经安装了几个库，包括xcode工具。当我在终端输入bash命令，我得到如下：

-bash：$：找不到命令

回声$ PATH：

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

我是否需要以某种方式改变我的路径以查找命令？谢谢。

你似乎打字$。这不是一个bash命令。
