Question

所以我想做一个bash脚本，但每当我运行它时，我都会遇到“错误的替换”错误。我已经浏览了stackoverflow并尝试了一些解决方案但没有工作：/ 有什么想法吗？

#!/bin/bash
printf "Hello. This is an OTS setup script provided by Damon at Otland. Please standby as user input may be required."
read -r -p "Do you want to install the webpanel? [Y/n]" response
 response=${response,,} # tolower
 if [[ $response =~ ^(yes|y| ) ]]; then
    wget https://raw.githubusercontent.com/NicolasLoew/vps/master/panelsetup.sh
    sh panelsetup.sh
 fi
 printf "If you installed webpanel please navigate to http://yourip:2004/ and follow install instructions."
 printf "Once you have installed the webpanel login and go to Enduser-->Configuration-->Apache and delete everything in the config and replace it with https://raw.githubusercontent.com/NicolasLoew/vps/master/apacheconfig. This will be needed for Znote later."
read -r -p "Do you want to compile latest TFS? [Y/n]" response
 response=${response,,} # tolower
 if [[ $response =~ ^(yes|y| ) ]]; then
    wget https://raw.githubusercontent.com/NicolasLoew/vps/master/tfsauto.sh
    sh tfsauto.sh
 fi
 printf "You have successfully compiled TFS! You can start it by going to cd forgottenserver and execute ./tfs. Dont forget to configure config.lua though. You can create database in webpanel-->enduser."
 read -r -p "Do you want to install ZnoteAAC? [Y/n]" response
 response=${response,,} # tolower
 if [[ $response =~ ^(yes|y| ) ]]; then
  wget https://raw.githubusercontent.com/NicolasLoew/vps/master/znotesetup.sh
  sh znotesetup.sh  
 fi
printf "You havee successfully setup ZnoteAAC. Navigate to http://yourip and follow the instructions."

根据评论进行修改

编辑被调用为

sh otsetup.sh

您使用sh而不是bash调用脚本。

用于将字符串置于小写

的参数替换

response=${response,,} # to lower

仅适用于4.0版本的bash

因此，要么使用现代bash调用脚本，要么使用不依赖于bash的语法。

例如

response=$(echo "$response" | tr '[:upper:]' '[:lower:]')

使用bash时出现错误的替换错误
