问题描述

在本地ddev实例中,我向 .ddev / homeadditions / bash_aliases 添加了一些别名和功能。

In a local ddev instance, I have added a few aliases and functions to .ddev/homeadditions/bash_aliases.

例如: alias ll = ls -lhA

同时 ddev ssh 然后 ll 将起作用, ddev exec ll 返回

While ddev ssh and then ll will work, ddev exec ll returns

bash: ll: command not found
Failed to execute command ll: exit status 127

为什么?

推荐答案

这实际上与bash的工作方式有关,而不是ddev的工作方式。 .bashrc(因此由.bashrc加载的.bash_aliases)仅由 interactive 外壳程序(如 ddev ssh 这样的外壳程序加载)。这是一个关于堆栈溢出的答案:为什么非交互式Bash Shell中的别名不起作用

It's really about how bash works, not about how ddev works. The .bashrc (and thus .bash_aliases, which gets loaded by .bashrc) is only loaded by interactive shells (contexts like ddev ssh). Here'a an Stack Overflow answer on it: Why aliases in a non-interactive Bash shell do not work

ddev exec 只能执行 bash -c< your command> ,而 bash -c 在设计上是非交互的。

ddev exec just does a bash -c "<your command>", and bash -c is noninteractive by design.

您可能会考虑添加ddev自定义Web命令来处理您无法摆脱的生活。

You might consider adding ddev custom web commands for things you can't live without.

A ddev ll 定制命令可以像这样工作。在.ddev / commands / web中使用内容创建一个名为 ll的文件

A ddev ll custom command could work like this. Create a file named "ll" in .ddev/commands/web with the contents

#!/bin/bash

## Description: Run ls -l inside web container
## Usage: ll [flags] [arguments]
## Example: "ddev ll"  or `ddev ll /tmp`

ls -l $@
