呼应-e在终端下工作，但不是在bash脚本 [英] echo -e working in terminal but not in bash script

问题描述

我公司开发和维护称为Githug红宝石的宝石，我想纠正一个自动化测试脚本它。 Githug基本操作一个文件夹，把它变成一个工作Git仓库的不同状态，并可以执行Git命令解决的水平。

I developed and maintain a ruby gem called Githug and I am trying to right an automated test script for it. Githug basically manipulates a folder to put it into different states of a working git repository and you can execute git commands to "solve" the level.

一个水平的要求你的混帐配置细节，我做以下内容：

One of the levels asks you for your git config details and I am doing the following:

#! /bin/sh
# ...snip
#level 4
FULL_NAME=$(git config --get user.name)
EMAIL=$(git config --get user.email)
echo -e "$FULL_NAME\n$EMAIL" | githug

当我从一个bash脚本它（回声-e）不起作用执行。但它确实，当我从终端运行它。

When I execute from a bash script it (echo -e) doesn't work. But it does when I run it from the terminal.

FULL_NAME=$(git config --get user.name)
EMAIL=$(git config --get user.email)
echo -e "$FULL_NAME\n$EMAIL" | githug
********************************************************************************
*                                    Githug                                    *
********************************************************************************
What is your name? What is your email?
Congratulations, you have solved the level

为什么不这样从bash脚本工作？

Why doesn't this work from the bash script?

感谢。

推荐答案

错误的家当：

#! /bin/sh

当它应是一个bash脚本，用

When it shall be a bash script, use

#! /bin/bash

Bash有一个buildin的回声，这是不是100％，同文同/斌/回声。

Bash has a buildin echo, which isn't 100% identic with /bin/echo.
