如何在 Linux shell 脚本中提示是/否？ [复制]

Question

#!/bin/bash
docker rm -f $(docker ps -qa)
docker rmi -f $(docker images -q)
docker volume rm $(docker volume ls -q)

sudo docker run -d --restart=unless-stopped -p 9090:80 -p 9091:443 --privileged -v /opt/rancher:/var/lib/rancher --name=rancher_docker_server rancher/rancher:latest

我想在这部分，在sudo docker出现一个问题之前是否继续？

Answer 1

试试这个：

echo -n "Do you want to continue [Y/n]: "; read choice

if [ $choice == 'Y' ] || [ $choice == 'y' ]; then
sudo docker run -d --restart=unless-stopped -p 9090:80 -p 9091:443 --privileged -v /opt/rancher:/var/lib/rancher --name=rancher_docker_server rancher/rancher:latest
fi
