为什么非交互的Bash shell的别名不工作 [英] Why aliases in a non-interactive Bash shell do not work

问题描述

我想在一个非交互式bash shell中使用别名。我已经定义我的别名，在〜/ .bashrc中我已经设置变量 BASH_ENV =〜/ startUpFile 。该startUpFile的内容源的〜/ .bashrc 。

I am trying to use aliases in a non-interactive bash shell. I have defined my aliases in ~/.bashrc and I have set the variable BASH_ENV=~/startUpFile. The contents of the startUpFile are source ~/.bashrc.

我可以看到我的别名被识别，当我执行别名命令。但是，如果我尝试使用〜/ .bashrc中定义的别名，Bash可以不承认它。它给我未知命令错误。

I can see that my aliases are recognized, when I execute the alias command. However, if I try to use an alias defined in ~/.bashrc, Bash can't recognized it. It gives me the unknown command error.

通过tcsh外壳是pretty容易做到这一点，因为〜/ .cshrc中文件始终读取。

With the TCSH shell it is pretty easy to do this because the ~/.cshrc file is always read.

任何想法如何，我可以用Bash shell中做到这一点？

Any ideas how I can do this with a Bash shell?

推荐答案

命令禁用了javascript -s expand_aliases 将允许非交互shell别名扩展。

The command shopt -s expand_aliases will allow alias expansion in non-interactive shells.
