Mac OSX：沒有找到bash命令

Question

我是一個新手 - 我有一個新的與El Capitan和系統python安裝的iMac。我已經安裝了幾個庫，包括xcode工具。當我在終端輸入bash命令，我得到如下：

-bash：$：找不到命令

回聲$ PATH：

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

慶典後-x -l：

我是否需要以某種方式改變我的路徑以查找命令？謝謝。

你似乎打字$。這不是一個bash命令。
