dash(Debian Almquist SHell) Ubuntu 自 6.10 后，将先前的 bashshell 更换成了dash (有待考证). 在设置 dash 的说明中有下面文字：

The default /bin/sh shell on Debian and Debian-based systems is bash.However, since the default shell is required to be POSIX-compliant, anyshell that conforms to POSIX, such as dash, can serve as /bin/sh. You may wish to do this because dash is faster and smaller than bash.

大致意思是说默认的 shell 是 bash shell, 但只要是能兼容 POSIX 的 shell 都可以，而dash 比 bash 速度更快、更小巧，因此 Ubuntu 安装了 dash.

怎么能把 dash 去掉而使用默认的 bash？使用如下命令：

sudo dpkg-reconfigure dash

此命令是对已安装的包进行重新配置，在菜单（dash-bash-sh.png）中选择是否将 sh 链接到 dash (Install dash as /bin/sh?) 选择否即可
