.bashrc:16: command not found: shopt配置環境變量時出錯

source .bashrc
-------------------------------------------------------
.bashrc:16: command not found: shopt
.bashrc:24: command not found: shopt
.bashrc:108: command not found: shopt
/usr/share/bash-completion/bash_completion:35: parse error near `]]'

使用另外一臺裝的biolinux系統的文件時，想更改下環境變量，習慣性地在.bashrc文件中進行了配置。結果出現了上面的錯誤。

谷歌了下，biolinux系統默認的shell是zsh.

echo $SHEL
---------------------
/bin/zsh

echo $Shell發現默認的確實是zsh。因而將環境變量在.zshrc中配置後source，成功。
