Update specific text in file from shell script
问题
我正在尝试在shell脚本中从用户提示中更新文档中的特定条目。用户应该被提示输入他们的域名，然后脚本应该更新3个不同行上的'yourdomain.com'部分。文本文件的名称是.env
IMAGE_REPO=tacticalrmm/
VERSION=latest
TRMM_USER=username
TRMM_PASS=password
APP_HOST=rmm.yourdomain.com
API_HOST=api.yourdomain.com
MESH_HOST=mesh.yourdomain.com

这很容易，您可以使用sed命令来从shell脚本中更新.env文件中的特定条目。
#!/bin/bash
read -p "Enter your domain name: " domain
sed -i "s/yourdomain.com/$domain/g" .env
echo "Updated values:"
cat .env
