如果有格式不正确

方法一：使用 dos2unix 转换（推荐）

安装 dos2unix

yum install -y dos2unix

使用 wget 下载
# 对于 CentOS 7
wget http://mirror.centos.org/centos/7/os/x86_64/Packages/dos2unix-7.4.0-1.el7.x86_64.rpm# 对于 CentOS 8
wget http://mirror.centos.org/centos/8/BaseOS/x86_64/os/Packages/dos2unix-7.4.2-1.el8.x86_64.rpm# 对于 Rocky/AlmaLinux 8
wget https://download.rockylinux.org/pub/rocky/8/BaseOS/x86_64/os/Packages/d/dos2unix-7.4.2-1.el8.x86_64.rpm

转换文件格式

dos2unix k8s-pv-pvc-manager.sh

重新运行

chmod +x k8s-pv-pvc-manager.sh
./k8s-pv-pvc-manager.sh

方法二：使用 sed 命令删除 CR 字符

# 删除 CR 字符
sed -i 's/\r$//' k8s-pv-pvc-manager.sh

重新运行

chmod +x k8s-pv-pvc-manager.sh
./k8s-pv-pvc-manager.sh

方法三：使用 vim 转换

用 vim 打开文件

vim k8s-pv-pvc-manager.sh

在 vim 中执行以下命令：

# :set ff=unix
# :wq

重新运行

chmod +x k8s-pv-pvc-manager.sh
./k8s-pv-pvc-manager.sh

方法四：重新创建脚本
如果上述方法都不行，可以直接重新创建脚本：

# 删除原文件
rm -f k8s-pv-pvc-manager.sh# 使用 cat 命令重新创建（确保在 Linux 环境中执行）
cat > k8s-pv-pvc-manager.sh << 'EOF'
